The California Assembly has approved a bill adding .50 rifles to the state's dangerous weapons list
"The Assembly approved a bill Wednesday that would add a high-powered rifle to the state's list of dangerous weapons. Under the bill, a criminal using the weapon would face up to 12 years in prison.
People who already own the gun would be allowed to keep them, but would have to register with the state Department of Justice.
'It requires a permit for people to buy them in the future,' [Assemblyman Paul] Koretz said. 'If terrorists want to buy them, hopefully we can catch them and prevent that.'
The bill was approved on a 42-26 vote, sending it to the Senate."
I refer you to an earlier post in which Michael Marks observed the California legislature as it contemplated a .50 ban.
