"do i have any rights as far as the way the polce conducted their job"
** Yes.
"my lawyer works for the pi and was once a police officer so he is not defending me at all"
** Do you mean the PI works for the lawyer??? Your 'version' would be unusual.... but not illegal or improper. And what is 'the PI' concern to you??
"he should be bringing the fact i was harassed arrested than un arrested asked to drive behid a buliding to be verbal abused"
** Who is 'he'?? The PI or the lawyer?? Who says you were first arrested, then 'unarrested'. It is very common for an officer to detain or even handcuff a suspect but that is not an arrest. And it is possible that the 'verbal abuse', though unprofessional, may have been deserved. What did you say to the officer to make him 'abuse' you??
