What you've described isn't "reality". It's your perspective or opinion, imaging a scenario that might be quite different than what actually went down, or their reasoning for pursuing Gray.
Let's remember he was arrested by cops on bicycles. Do you think they had police scanners in their bike helmets that used facial recognition software to scan Gray's face and pull up his criminal record, and then they decided he'd be an easy target?
Or do you think they maybe pursued and detained Gray because he sprinted away from them as if he was guilty of something, and they then had reason to be suspicious of this man and what he had done / was doing / was about to do?
We know that SOME police are biased. We know that SOME police are corrupt, but you are making an extremely broad generalization that is based on your own perspective and opinion, and not rooted in fact -- at least not based on what we know of this situation YET. How would you feel if someone said, "We are aware that black people are criminals and thugs"? Would that be fair perspective to have?
If I was a police officer patrolling an area with a high level of crime and a person spotted me and then fled, I think I would be justified in assuming that this person was involved in some kind of illegal activity, and I would certainly want to pursue him to find out why he fled or what was going on.
If you were a police officer in the same situation, would you not do the same, regardless of the person's skin color? Or do you think that when a cop sees something suspicious (like a person spotting them and sprinting away), that they should just give them a pass because they hadn't explicitly seen him breaking a law yet?
Remember that police exist not only to detain and punish people who have broken the law, but they also exist to prevent people from breaking the law, along with investigating suspicious people and activity. To use an extreme scenario, if the police had let Gray escape with no consequence and he then went on to murder someone, who would be in the wrong there?
Reports thus far indicate that Gray made eye contact with police and then fled unprovoked. Until proven otherwise, I'm not sure what you mean by "targeted like he was". It doesn't seem like police tried to arrest him and then he ran. Rather, all reports indicate it was quite the opposite.
Furthermore, if you were innocent of a crime and fled from police anyway upon making eye contact with them or even being approached by them, you'd only be making this worse for yourself and could possibly find yourself in a confrontation with police.
Do you not realize that fleeing from police under any circumstances can be considered breaking the law, regardless of other crimes committed? A criminal charge of fleeing or evading the police may be either a misdemeanor or felony charge, depending on the circumstances. For example, fleeing the police in a vehicle is a felony charge, but eluding the police on foot is usually a misdemeanor.
Also, you seem to indicate that you believe that the police actually have the power to arrest anyone they want at any time with made up charges. Does this mean you honestly believe that all 18 of Gray's previous arrests and convictions were not justified? That each time, police planted evidence, lied, forged documents, or bribed witnesses?

Your certainty is quite disturbing, that if he hadn't ran, he would have been arrested for just standing there. Sadly, we'll never know if you're right because he did run, which only served to give police reasonable suspicion that he was up to something.
