Can I sue a police officer for violating my right

You have no grounds for a lawsuit IMO.

I was at a bar hanging out and some idiot drops by and pepper sprays the entire inside of the bar and flees. CAN I SUE?

If you can find out who did it and can serve them, and they have any money, you can sue them.

It is the responsibility of the homeowner.

Can someone get in trouble for false accusations ?

You can sue him in small claims court.

This is not a legal issue, but a family one.

The man I married apparently has a wife in two states

Depends on what you want to do. Have you asked him?

IMO you have no grounds for a lawsuit under these facts.

If you want to be in your daughter's life, and you should, contact an attorney about filing for visitation.

Are you a civil rights lawyer?

The lawyers who volunteer to answer questions on AVVO cannot reach out to you. You can use the Find a Lawyer tab above.

Can I press charges on someone who recorded and has a video of me showing my private parts?

Very common scam. Block and ignore.
