It depends on what your definition of "works" is

Dem Sen. Cites Success of Gun Laws in California a Day After San Bernardino | Mediaite:

“Sensible gun laws work, we’ve proven it in California, and we’re not gonna give up.”

(H/T: Irons In The Fire)

I'm never sure where Barbara Boxer gets the statistics to back up her absurd announcements, but it's certainly not from the San Bernadino Sun:

At least 36 people have been killed in mass shootings in Southern California in the past four years.

California Legislators have been working overtime in recent years to impose ever more egregious Gun Control restrictions on honest citizens, and the net result is that the murders keep on coming with little or no reduction on the availability of firearms to nuts, kooks, madmen and just plain evil people. 

The funny thing (if the word "funny" can be used in the sense of "incomprehensible", rather than "humorous") is that many of the recent slaughters have been perpetrated by people who have jumped through the hoops of the most restrictive gun-control laws in the nation, and the killing continues without any obvious relief.

POLITICIANS like to think that their efforts at imposing ever-increasing infringements on the Second Amendment are "making a difference".   But laws won't stop mayhem.

They will stop honest people from being able to defend themselves, but they won't stop Bad guys.

Legislators pass laws .. it's what they do, it's what they were elected to do, and it's all they can do.

Laws have ZERO effect on murderers.

(NeverYetMelted makes the case that the weapons used in the San Bernardino shootings were not legally purchased by the killers.)

Oh yeah, Dave Workman has an article in The Examiner (Washington State) which suggests that a year-old gun control law (I-594) isn't doing what it was suppose to do ... stop guns from falling into the "wrong hands.

What effect these "gun control laws" DO have, is a negative impact on the ability of honest citizens to protect themselves.

So, if Barbara Boxer is determined to say that "gun laws work", the needs to go back to her original quote which says that "SENSIBLE gun laws work".

There's nothing very "sensible" about these laws, if you measure it by the actual effect on reducing crime.  Which is .... uh ...  the opposite of positive.

None of the gun control laws imposed on Californians have reduced the number of mass murders, or the number of victims.   The only way these laws can be said to have "worked" is that they accumulate to make it more difficult for honest people to defend themselves in public places.

The definition of insanity is trying the same thing over and over, and expecting different results.

By this measure, Barbara Boxer is certifiable.

And she's not gonna give it up.
