The problem with non-lethal weapons is, when those they are used against have only lethal ways to respond then their response will tend to be...well, lethal.
A couple of years ago a chap from AFRL demonstrated a mini-version of the ADS for me on my hand – it was most alarming.
Shine one at your average unhappy chap with an AK and you can be pretty sure you'll get a full clip back for your trouble, so what exactly does this achieve?
You can't point it everywhere at once and keep it on for half an hour, which is what's needed. And all you have done is really pish off the people you just attempted to broil, who won't make the same mistake twice.
What a waste of money – and, yes, what about leather coats??
