The following events happened to me from police. Were they fair?

One night at about 2:00 am I stopped to get the Sunday morning paper form a new stand in a strip mall. A cop asked me what I was doing there and asked for identification. I was jogging at the high school track after dark and a cop shined a light in my face and asked me what was I doing there. A cop stopped me for going to slow a few blocks from a bar; I had only had a half a beer but didn't want to p him. A cop pulled me over for suspicion of illegal tags just because I had not torn off the prior tags and somehow he thought the tags were illegal. He subsequently pulled off the tag and accused me of the tag being stolen when it was not. A security guard grabbed me when I was running through my former apartment when my only intent was to jog to get the mail. These events occurred even though I am a blond-haired blue-eyed college educated white male, If I had been black would I have thought racial profiling was involved. And most likely in any of these cases if I had been belligerent and talked back to the cop I probably would have been detained or arrested. Despite your race, you CAN NOT talk back to the cops with ANY disruptct despite your race. This is when many of the more serious incidents occur. I am not saying it is right (in fact it is not), but that is the way it is.
