Why didn't Connecticut and New Jersey's restrictive gun laws prevent this mass shooting?

Because the problem isn't with the second amendment, it's in our psych.

If the information released thus far is accurate, the federal gun laws were violated as well.

You must be 21 to purchase a handgun and all reports I have seen give the age of the shooter at 20.

I take no sides between the gun fetishists and the gun grabbers on this one, but the problem here will not and cannot be legislated away.

Because they’re NOT restrictive.

Japan, which had 2 gun deaths in 2006.

To get a gun in Japan, first, you have to attend an all-day class and pass a written test, which are held only once per month. You also must take and pass a shooting range class. Then, head over to a hospital for a mental test and drug test (Japan is unusual in that potential gun owners must affirmatively prove their mental fitness), which you'll file with the police. Finally, pass a rigorous background check for any criminal record or association with criminal or extremist groups, and you will be the proud new owner of your shotgun or air rifle. Just don't forget to provide police with documentation on the specific location of the gun in your home, as well as the ammo, both of which must be locked and stored separately. And remember to have the police inspect the gun once per year and to re-take the class and exam every three years.

gun restriction laws are an open invitation to the crazies to come shoot the place up.

You notice these things don't happen in states that encourage people to have weapons.

You forgot to mention that guns are banned from schools

you also forget that in all states elementary schools have gun bans.

Why don't we see where the gun came from first.

I think it would have been prevented if someone was closer and could have helped out!

If a mad man is intent on murder, he will find a away to do it.

Uh, because neighboring states don't have similar laws?
