No surprise that he said his civil rights were violated ... however, is he willing to take the case on contingency? Or, is he demanding payment up front? If he wants payment up front, the case may not be as strong as he is letting you think.
Keep in mind that a lot of these cases start with a claim to the agency involved, and the plaintiff hopes for an out of court settlement - usually an offer for less than the agency thinks it will cost to fight the case ... in my experience these sums are between $5,000 and $10,000. However, if the city denies the claim, then you will be in a position of paying the attorney for his time, for depositions, for court appearances, and for a lot of effort that might not result in a payoff in the end.
But, the devil is in the details. And since in my state we don't have such civil citations, I can't quite fathom how possession of drug paraphernalia is NOT a crime. If this was a blatant, egregious, and unreasonable act on someone's part, then chances are they will pay the initial claim. if not, you're in fro a long drawn out deal that could cost you a great deal of money.
So, have you and your son discussed his drug use? Perhaps a couple of days in jail will actually have been to his benefit - maybe he'll think twice about being around dope again. Had it been my son, I'd tell him to chalk it up to a life lesson and wouldn't be putting out a penny for his claim/suit. But, that's me.
