I, and most of the people who live in the real world, understand that nothing could have been done to prevent this. He broke no laws in his preparations. Purchasing ammunition in bulk is done by most shooters because it is cost effective. No weapons were purchased off the internet and background checks were done(he passed). What "new" laws would you pass(other than depriving me the right to carry or own a weapon) to prevent something like this happening again??
