No, that's generally not right.
I don't ever see anyone argue that criminals will never get guns. Perhaps you can link someone who does.
The argument is that restricting access guns will limit the availability of deadly weapons and fewer people in total will die.
Hmm. Lets see...
CA gun laws require that:
-All transfers must be through a dealer, thus...
-All transfers undergo a background check
-All transfers undergo a 10-day waiting period (ruled unconstitutional 8/2014)
-All firearms must be registered
-Handgun purchases require a handgun safety certificate- a permit.that requires training and a test
-Ban on assault weapons, effective 1 JUN 1989
-Ban on magazines that hold more than 10 rounds
-Ban on NFA machineguns
