Obama technically has been saying that he doesn't want to take away the right to use guns for self defense. He would like to ban certain types of guns. Now we at JTF understand that this is a threat to the entire second amendment and the right to defend yourself. However liberals would not understand this and would take Obama at his word. As far as I know, George Zimmerman's gun didn't fall under the types of guns that Obama was pushing for banning.
Liberal or conservative, as a human being, Zimmerman had the right to defend himself and we shouldn't focus too much on his personal politics as that's not really the issue. In fact Zimmerman himself is not really the issue. He just happened to get thrown into all this to be made an example of.
