Why not mandate trigger locks and locked gun cases?

Well, I agree with current Florida law, which says that anybody that breaks into my home (i.e. enters without my permission), while I'm in it, is committing a violent felony, and yes, I do have the right to stop a violent felony with lethal force. That doesn't mean anybody in my house (i.e. dinner guests), and I have never heard a gun owner claim that. Nice strawman, but it's getting tiresome.

 

In other words, what is being advocated by yourself is causing carnage, to try and prevent carnage.

 

Carnage is what happens to my sarcasm from time to time.

 

Silly you. Completely unaware that No where in the constitution does it say anything about this.

 

I see you are ignorant of current jurisprudence. Allow me to help you with this:

The handgun ban and the trigger-lock requirement (as applied to self-defense) violate the Second Amendment . The District’s total ban on handgun possession in the home amounts to a prohibition on an entire class of “arms” that Americans overwhelmingly choose for the lawful purpose of self-defense. Under any of the standards of scrutiny the Court has applied to enumerated constitutional rights, this prohibition—in the place where the importance of the lawful defense of self, family, and property is most acute—would fail constitutional muster. Similarly, the requirement that any lawful firearm in the home be disassembled or bound by a trigger lock makes it impossible for citizens to use arms for the core lawful purpose of self-defense and is hence unconstitutional.
DISTRICT OF COLUMBIA v. HELLER (No. 07-290)
478 F. 3d 370, affirmed.

You are now fully aware of the fact a legal requirement to lock up your guns violates the constitution.
