I carry concealed everyday...why? to protect myself and my family from wannabe streetfighter/thugs/theives (like Trayvon Martin)
I'd really hate to live under constant fear like you seem to do.
Also, I fail to see how a firearm would make you safer. I mean, it's not like many criminals are out there with the intent to kill random people on the streets, not even in America.
Most people commit hold ups to get some money. Now if the general public isn't armed, the victim loses some valuables, perhaps a little pride (I wouldn't) and has to go through a bit of a hassle with the police, banks, credit card companies etc. All in all, a loss of time and money that's quite easily recuperated.
But if people are armed, there's a bigger risk for the robber than the punishment for breaking the law. Thus, not only is the robber more jumpy and nervous, he's also more likely to take rash actions like preventitavely wounding/killing you, before you could even reach for your gun. Not to mention he might misinterpret your actions and THINKS you reach for a gun instead of your wallet and "pops a cap in yo ***" just to protect his own life. (Which incidentally is a situation that makes you alot more likely to get shot by the police accidentally).
Also, IIRC, most gun related deaths in America and almost everywhere else happen in families, be them accidents or murders.
So, by my logic, owning a gun makes you and your loved ones actually quite a lot less safe. Even if you feel safer for carrying one.
But then you might call me a hippy, because I generally deem a human life (even of a criminal "low life") to be worth more than all the things I own. I'm not saying that such persons should go unpunished, but they shouldn't die.
Of course I could imagine resorting to violence if other people (their lives, that is, NOT their posessions) are in danger, but never with the intent to kill.
