What to do?

3. I don't totally understand the point you are trying to make

It isn't a gun problem as it is a drug prohibition, mental health, urban decay, historical, cultural and several other problems. Gun restrictions will do nothing to address these issues in the US anymore than they have in Jamaica or any place else.

What are these reasonable restrictions are those? Most of the suggestions I have seen either suggest the status quo without knowing it, or based on a total lack of technical knowledge (heat seeking bullets) or guns that are rarely used in crime.

May I suggest some military history classes covering

Registration doesn't do anything. That is why Canada dumped their long gun registry twice, after WW2 and this year. New Zealand dumped it in 1982 because the system was rife with errors and took money and cops off the street. There is no positive result unless you are the IT contractor.

What does invasive species have to do with guns or street crime?
