Again... I learned first aid because I may need to use it... wanna' give me shit about it?
People lock their doors because they "may" deter theft... I hope you did not buy new locks when you moved...
IMO, people who actually ruled their lives by statistics are more likely to look a lot like this:
People wash with anti-bacterial soap, but they don't put treads on their tubs and drive instead of flying... they worry about false fears and ignore what kills far more people more often...
Having a gun you know how to use handy is just safer. Hopefully you will never use it... but, hopefully I never had to use my self-defense training or gun... it has not worked-out that way. Glad I had both.
