With the wind down of discussion, let me add something that greatly bothers me on some posters' opinions on the facts.
I am that guy.
I am a guy who will check out something I think suspicious. I will look, hard, at people doing things I think need a closer look. I am a guy who has an emergency kit AND a first aid kit in the trunk of my car. I used to call the emergency kit an earthquake kit, but I added flares, jumper cables and a can of fix-a-flat so it's now an emergency kit. I will flare up an accident, jump start a car or hand over the can to anyone who needs it in a heartbeat. If that heartbeat stops, I am confident in my skills to do what any trained person without equipment can do to help and if it is only a boo-boo, I have the cold packs, dressings or splints to deal with those as well. I will lift other people's kids off the store display and chastise them if they are being a nuisance. That includes teenagers in groups. I always stop and buy something from kids who set up a stand on their own, even if I don't want any Kool-aid, lemonade or cookies because that's what I think a good neighbor does. (This rule does not apply to parent set up tables outside of stores to sell mass market items.) I will spend time trying to catch a roving dog, even if I am in a suit and its raining out. I take pictures of lost animal posters in the neighborhood, just in case I find what they are looking for.
Not only am I that guy who would do those things, I have done all those things on more than one occasion.
I go on patrol of my neighborhood twice a day and have called the police, caused people to run when I did my looking, got explanations from people who knew what they were doing was odd and had a couple of verbal run in's with ne'er-do-wells who seemed to think better of it when the phone came out as well as a laugh or two when I realize I was wrong. Now, I don't carry a concealed firearm as my state is rather restrictive on such things—but I would if I could. (If I did, I'd go to the range at least twice as much as I do now.) Sure, I have a little false bravado on my patrols from having two large pit-mixes with muscles on muscles with a combined weight of about 150 to 160 who stay about six feet away from me at all times. But, while scary looking, I suspect the only real help they would be in a true confrontation would be to give me kisses after I had my hat handed to me by some youngster. While I might have a trick or two up my sleeve that would require the youngster to be quite serious or find they might have underestimated the power of old age and treachery, they are simply tricks. A determined assailant would win.
What is suspicious? I don't know how to describe it. But, through the years, I've probably walked the non-gated neighborhood of about 800 homes 2000 hours along with driving to and from work, the market, church or any of a number of places. I know what it looks like and what the people look like and what their cars look like and what they do in their front yards and how they move between yards and...well and any of a number of things my brain has picked up on but has not notified me of as yet. I haven't seen everyone who lives there or all of their guests or all that they do, but I certainly have a sense of what is odd or suspicious. I bet you do for your neighborhood too. Some of my subconscious learning may be enhanced by the fact I am always alert when outside. I am always looking around, seeing, noticing.
While I have no idea of the true facts in the Zimmerman case, I know some have complained about him doing some things in regards to what he thought was suspicious behavior. That scares me a bit. It scares me more than a bit some want to criminalize behaviors I do all the time because of the independent actions of another party. Things I do because that's what I think I should do. I call it being a good neighbor. Some others here seem to call it something else.
LOL!
