the problem is the line of thinking that o yeah 21 is a reasonable age.. thats how they will get their foot in the door and then the next time it happens they will say we didn't do enough and push for more.. so on and so forth. Also some lib congressman and 167 co sponsors just introduced a new "assault weapons" ban and boy oh boy is it an extensive list.. screw these guys. Im not for changing any ages or a single gun law. Fix the real problem, Fix the fact that this dipshit kid had the sheriff there some 45 odd times, the fbi tips, so on and so forth. Maybe pass a law or figure out how to get law enforcement agencies to communicate with each other.. the fact that the alarm was raised on the kid this many times and nothing was put in for his background is a disgrace. changing ages, restricting magazines, banning this gun or that gun or all guns will not ever solve the problem. the real fact is that there are sick little freaks out there that will do terrible things no matter what law anyone passes. they'll do it with a gun, knife, a u-haul truck, a cup of acid or a louisville slugger.. so no 21 is not reasonable, *unless* you also cannot: serve in the military, be tried as an adult, drive, pay taxes, serve on a jury or vote. rant over.
