I can imagine a situation where I would need first aid knowledge. ( i do have it, but here it works different, even if you are certified and you do save a mans life, or women, they can still sue you because They are sore for CPR, or what have you) Anyway, I'm taking my leisurely stroll down the road enjoying my first amendment right to free speech, and ..I tell my neighbor what i think of his dog crapping on my car tire...and ..The man obliges himself to assault my fist with his face... Well after about 5 minutes of enduring this assault, i might need to preform some kind of first aid on his person to ensure he doesn't choke to death.. .....Don't ask where that scenario came from ... *whistles innocently* g-man
