And with the # of crimes rising all over the place, i find it strange that so many people are willing to trust their own safety to cops, who are often 5+ minutes away.
People can cover the actual lowering of crime, but I'm going to cover the "Safety" argument.
If the idea is, you'll be protecting yourself from a home invader, maybe you should look at one of the most basic tactics of home robberies. Now the stereotype is, it's 1am, a guy in a ski mask slides open a window with a flashlight and slips into your room looking for your jewels, or whatever people have they think is worth killing over.
But the reality is, most robberies happen during the day time... while the occupants should typically be at work. Because they're robbers, not killers, they don't want a confrontation, they want your stuff! They're average people, like most of us, and they don't want anyone to get hurt, themselves especially.
BUT! You maybe thinking, "What if they break in and are surprised to find you home rather than at work?! Huh smart guy!? Huh handsome?!" ... sorry getting off track.
Well that's where the robbers greatest weapon comes in... they knock on your door, they ring your doorbell. They get an answer? "Oh... sorry, I must have the wrong address..." Time to walk away.
They don't get an answer? Time to play a game called peekaboo! Check the windows, see if you find anyone, and if you don't, find something unlocked.
Get this, if they find something locked, they'll probably just walk away. People robbing houses aren't lock pick experts, and breaking windows is to noisy.
If you're concerned about serial killers, that's just irrational, statistically. Odds of being killed by a gun assault in the U.S are 1 in 370! Where the odds of being killed by a serial killer are astronomical! Greater then winning the lottery, which puts you somewhere in the 1 in 14 million range.
And if it's personal vendettas people are worried about, I think that requires a lifestyle change, rather than a .38 snub noised in your glove compartment.
Murders most often aren't premeditated. They're quick, spontaneous acts of violence. Most often committed by and to, two people familiar with one another.
Statistically, I'm most likely to kill my spouse, not some random stranger. ME! The greatest thing I can do to protect her, isn't own a gun. It's not be a scum bag.
