Robert from Springfield, MO has done his time and paid his debt to society. As a free man and a family man, he turned to Byrna to protect his family after discussing with his attorney and double-checking with local laws and regulations. His Catholic background and time served has taught him that ending a life isn't something he desires to do yet wanted to confirm a viable option would work for him.
Robert confesses that while in prison he was on the receiving end of various other less-lethal tools like a beanbag round and rock salt, but to put it in his words "I would much rather get hit with a taser any day than to get with this SD."
