> rampant mass shootings and bombings like they do in Europe

Europe has "rampant" mass shootings and bombings? They are very rare, despite the media coverage. The U.S. has many more mass shootings, AFAIK.

> do you want the government to be proactive and work to flush these people out from the shadows before they commit a terrible act and murder innocent citizens?

The question is whether many of these people would commit crimes if not for the instigation of law enforcement.
