Of things to provide a defense for women in particular/ there is one method, to consider: of establishing a perimeter that would be effective.
It is described as “using a vest” for simple purposes. This vest is outfitted with: a small scale exploding devise; backed by a steel plate holding “the firecracker”, of suitable size: placed against the wearer to force the explosive event outward/ not inward. When exploded a suitable deterrent is moved from the vest containment: when placed on the back. The deterrent is directed onto the person behind. A fire retardant powder placed around the exploding device should be enough to quell any threat of unintended consequences. Rather like opening a “ketchup packet at the restaurant”: To paint, and to scream with noise, and to inundate someone too close with “itching powder/ vomit inducing mucus/ or coughing and sneezing powders” such as will be: ABSOLUTELY NOT. To any attacker. for effect: you can place a ketchup packet on a table and hit is with a hammer. “to consider the result”.
The method of release should be electrical; so that it is released if an attack is made by “electrical means”. The best methods would be; a warning devise such as motion detection; to prepare the woman/person involved. And there should be a suitable video capture; sent immediately to “the internet”; through your phone; if motion is triggered that could be considered harmful. With the decision involved of the person wearing the vest/ or not in the case of violence. These can be accomplished electronically. Particularly suited to runners. And these devices can be incorporated into clothing or coats; with venting pockets or flaps/ seams; (even directional seams) that will open, or other. You can incorporate the device into purses or hats or canes or whatever seems of value to you. BECAUSE MARKING SOMEONE FOR COURT is a deterrent/ just like releasing a scent recognized as yelling for help; is also effective. As is painting them with florescent paint; and so on.
BUT there is, like nearly all elements of “anything that can be used by you can be used against you”. The critical reality of more aggressive explosives that can damage, blind, or even kill; with this device altered; those who are unintended victims. As such even with the element of use that is subject to review; there should be an insurance policy; that buys those who have experienced harm of some kind: a suitable element of cost reimbursement.
The claim of “less lethal”; is misleading/ as those weapons can do a body great harm or kill someone easily; particularly if you hit them in the face. The more crucial method is: to replace lethal bullets, with less lethal marking bullets; to establish “this is the man” in court. Which requires a police report; so that you are marked too.
Even so; as with all guns: they are far more likely to be used against you/ than by you. Because an attacker “intends to take you by surprise”/ and has the advantage from the beginning. So even if you have a gun in your hand/ it is not likely you will use it. Or if you do; someone unintended will be harmed or killed.
OR MORE SIMPLY; as nature has established with the skunk: deterring an attacker/ is just as functional as hurting them. Even if “women” scream; I want him dead/ IT IS FAR BETTER TO SIMPLY HAVE AN ATTACKER STOPPED. As the skunk effectively proves; “leave me alone/ I ain’t worth the price”. To far larger and aggressive predators. And if they don’t: they are marked for identification/ so that all the others in the area know. As is a skunk released scent; can be identified easily from a mile away/ and pinpointed as to direction, and basic distance; to identify; where he or she is.
A suitable wire or other packet opening or directional device can be placed over the packet; with the explosive device under the packet. So that when detonated; the packet is pushed into the “opening device”. Is to be consider common to the purpose required. Kevlar or other can be used instead of steel/ but all will leave a mark; and can be used for identification. “good (helped me) or bad (you were wrong)”.
Devices can be activated by “pulling a string” or other. But if “attacked electrically”; the response should include a simple: co2 cartridge (as is used in some pellet guns), whistle attached to the gas escape nozzle/ activated by a cam that rotates to open the gas; thereby screaming “help”. That literally cannot be turned off, for several minutes.
If the screamer is handheld; a lever can open it/ and a suitable packet of identification; can be squeezed into the gas stream to aid in forcing the attacker off/ or at least becomes courtroom evidence. Different colors or other; would indicate the amount of pressure required to open the whistle response. As not all need the same.
Other methods of releasing such a scent/ or describing “IT ONLY HAS TO BE RECOGNIZABLE”. AS IS yelling “fire” for instance/ so that everybody knows, this scent/ this noise “means that”. help is needed! have been rejected, in my past. “got a brain yet”?
But as always; women and others rejected that; because they don’t want to do it. Unless of course, they are attacked. in which case they scream: I don’t want to stop them/ I WANT TO KILL THEM. a failure of pride.
I find no purpose in filing with the organized crime and thieves; that are called: “US patent office”. just a different disguised by deceit; criminal thug. This is free if you protect it; your choice.
And as always the world screams back: “WE CAN’T READ; we are believers; UNIVERSITY is our god”/ TO HELL WITH YOU. Because after all; the university is your god, and as cult followers/ you have no brain; “believers (truth does not matter)” instead. As evolution and covid and weapons of mass destruction are your saviors, and much more exist to prove: you cannot refuse what the leader tells you to believe. And to prove “you are a thinker”/ gossip is claimed to be all you need to know.
Pride does that! To scream: I KNOW & convict and determine/ to judge and deny any form of trial; before sentencing. Because it is far easier to believe whatever you want to believe/ than to examine the evidence and prove what is true. And the cost of that is: that people can be very effective liars/ traitors/ and thieves. Always doing their best; not to be caught or convicted of what they did do. Consequently a percentage of those who are innocent; will be tried and convicted of things they did not do. Beware that you are not someone who fails justice/ and does great harm. Because there is no going back “when you pull the trigger” on a gun. FEW “know”/ but repetition is one form of understanding: “look harder”.
