As a result of having more situational awareness as of late, I'm noticing the things that don't fit. For instance, I drove by a large woman beating up a small man the other day. I called that in. Tonight I drove by a tall guy walking purposefully across the street in a known drug area with a canvas jacket slung over his right side. It's 82 degrees. Looked not right to me. Looked like a great way to conceal a long gun. I kept driving and called it in. So my question is this: do I call LE about this stuff? Is it helpful? I'm no Rambo and go the other direction, try to be a discrete but good witness. But in calling in "suspicious activity" am I helping, or hurting, or neither? If it's near my home or my office, my threshhold to call in is lower. Opinions? Facts?
