So the FBI released some data yesterday on gun violence against cops and there was this nice little piece of information in there
Predominately handguns were used in the assaults on officers and all but one were obtained illegally, usually in street transactions or in thefts. In contrast to media myth, none of the firearms in the study was obtained from gun shows. Researcher Davis, in a presentation and discussion for the International Assn. of Chiefs of Police, noted that none of the attackers interviewed was "hindered by any law--federal, state or local--that has ever been established to prevent gun ownership. They just laughed at gun laws." http://www.forcesciencenews.com/home/detail.html?serial=62
Don't forget though boys and girls gun laws are there to protect law abiding citizens because criminals will obey laws that we put in place.
