Arguments that Swiss gun owners are well vetted by their military service seem rather irrelevant since about 81-89% of those who commit gun crimes in the US did not purchase their weapons legally—thus what good does vetting for a legal purchase do anyway? Whatever the problem is, it has to do with why there are crooks who want to get their hands on a fire-arm and commit crime with it and not anything to do with vetting legal purchase of fire arms.
“... about 81-89% of those who commit gun crimes in the US did not purchase their weapons legally...” Thus the need for more background checks for law abidin.............. Oh?!
