Modern liberalism is based on the idea that reality is obligated to conform to one's beliefs because; "I have the right to believe whatever I want".
"Everything the State says is a lie, and everything it has it has stolen.
-Friedrich Nietzsche
"Every time something really bad happens, people cry out for safety, and the government answers by taking rights away from good people."
-Penn Jillette
A World Without Guns <- Great Read!
Which wouldn't have limited our legal options one bit when they inevitably broke their word.
30 would have put the ban outside of common use as 30 rounders are common use for the AR/AK platforms giving us less standing. Would have been harder to challenge that. If the debate was between 30 and unlimited it was foolish to let 15 win.
I think the answer is going to come out of CA or NY and should apply to all states. NYSafe was already ruled an arbitrary ban at 7 rounds. It's 10 now but no less arbitrary, just what some judge thought was reasonable. No modern pistol/rifle, as issued, has such a limit that I know of (maybe .50BMG and shotguns).
