If 3-4 people, other than Rawls, came onto the private property where Owens was, in a mob, then they are all guilty of criminal trespass at minimum. Since Rawls beat Owens and is charged with first degree assault (assuming it included assault with intent to main, if not it should be added to assault & battery with a weapon), then the others are accessories before the fact.
If they can be identified, then one of them will roll over rather than fact 10-20 years in jail.
In fact, Rawls should be charged with attempted murder (a greater charge than assault), assault with a deadly weapon, inciting a mob to violence, and criminal trespass (or the Alabama equivalent to those charges).
A lot of people know who was in the mob and where they came from. Sounds like either poor police work, or a lack of will to do good police work. Is Williams a Holder Jr.?
Right, if one of them can be identified...
Hence, the problem. Nobody is talking.
You also need more than a simple accusation to make an arrest, because the police do have to consider the possibility that somebody has it in for the suspect and is making a false accusation, even if the person making the accusation is the man’s sister.
