Personally, I don't think that the police officers' actions directly led to this man's injuries and subsequent death, but in the end it won't really matter and here's why:
1) The mobs of local degenerates believe whatever rumor they are told first by the handful of "leaders" that they actually listen to ("reverends", "community activists", ex felons with names like Something-X etc.) and have neither the capability nor the willingness to listen to facts, and the concept of impulse control isn't something they have any semblance of.
2) This man very may have been arrested for something that was not in fact against the law. In Maryland, you can openly carry an auto, but not concealed. Baltimore city bans auto possession entirely, but evidence is beginning to suggest that this man did not in fact have an auto but rather an assisted opener. Only in Ocean City are these illegal. Surprisingly, Maryland state knife laws are actually not very restrictive at all (no size limits, it's either a "switchblade" and illegal to carry concealed or it's not), some localities have additional restrictions though.
3) If he was in fact arrested for something that was not in fact a crime, they violated his civil rights under the 4th, 5th, 6th, 8th and 14 Amendments in doing so. Even if he were alive and had not sustained any physical injury, he would have a very valid case against the department and the city. That would be one that usually would be settled for a sum in the 5 figures. Escalate it now to include violating civil rights resulting in his death and the numbers grow astronomically. I can see this costing the city several million in the end.
4) There really won't be any winners, except the attorneys who represent the family. They will take roughly 40% of the settlement amount, plus expenses, before taxes. The family who get the remain sum will likely squander it on things like a clothing line and a record label and well just generally wasting it. Rodney King got something like $6M from LA and ended up dying completely broke...and he's not a rare case...
