A European Union spokesman has acknowledged "serious loopholes" in the bloc's current rules on the acquisition and possession of firearms, but said the EU's executive has submitted proposals for tighter regulation.
This is the problem when gun "control" laws are the primary, sometimes only, response to violence. Considering mass violence is often born of untreated mental illness or unsupervised pharmacological experimentation, not to mention religious extremism, and realized not just with guns but with bombs, axes, machetes, knives, and trucks, I doubt much is going to change.
As I remind the reader, laws only control the law-abiding. Criminals, lunatics, and terrorists are, by definition, outlaws.
