thank you very much, i'm dennis oleary from the chief's office. first i would like to let you know that the question was what are the four more commonly enforced gun laws in san francisco? and now, commissioner mazzucco they have changed the laws and the numbers are different. so what used to be like 12025, and 12031 is now a new series. but any way, the most common guns are carrying concealed with firearm and carrying a loaded firearm, someone that is prohibited from carrying a gun is caught carrying a gun and then carrying a stolen gun and that is what the 496 charge is. and california has like angela was saying, has some of the most restrictive gun laws in the state that makes it and it is difficult to buy a gun, where people have to in california, the firearms dealer has to be licensed and there is background checks and ten-day waits. that has been standard for many years. and there are limits on how many guns can be purchased and it goes on about the record keeping and particularly it talks about our gun laws penalize access for children due
