Thats the thing. It doesn't. It improves your chances of pissing off your attacker by 100%. If you take your self defense seriously, book a firearm training class tomorrow and start the long process NOW of obtaining a firearm for self defense. In fact, a knife i think is more effective than your non-lethal choice.No offence taken. But if having a Byrna ups my chances from 0 to 1 %, then it’s 1% more than I would have had without it.
As previously mentioned, I’d rather have a fighting chance with a pepper ball or 5 than standing holding my dick in my hand.
