"please make it known to all of us if you support any reasonable law or action to diminish mass shooting attacks"

1. Show me the law and tell me how it reduces the risk of mass shootings.

"just yes or no is fine"

Not reasonable- "Have you stopped beating your wife- yes or no?"

I would support new laws IF I have reason to think that

1. They would be enforced fairly.

2. They would be effective in doing what they are put in place to do.

3. They would inflict less damage than the actions they are trying to prevent.
Obviously, a government search and seizure from ALL homes, places of business, and private property of ALL firearms and ammunition would reduce the chance of mass shootings- but the riots that would occur might well kill a lot more than the shootings.
But then, if we can't keep 11 million illegal aliens from entering the country, how can we keep out the ( then illegal) firearms? We need a bigger wall, to prevent re-arming of those who desire guns ( present criminals and the new criminals that would resist the confiscation.)
