Sue them

The relatives of all these gun massacres over the last 12 months should sue the US Government and the gun manufacturers. Sue them until they suck them dry. Sue them both for negligence and the government for refusal to legislate.

Relatives of those who died of lung cancer effectively sued the tobacco industry, draining them of money while legislation changed.
The same thing can be done here.
It’s time we properly vilify the gun industry and shame anyone that supports it.
