Can neighborhood watch detain you and force identification ?

There's a lot to unpack here, but suffice to say that you should contact an attorney. What happened was a tort known as false imprisonment. One person can detain another if they see the other person committing a misdemeanor, or has a reasonable suspicion that they've committed a felony. That doesn't appear to be the case with you, and as such, the detainment could very well be unlawful. IN ADDITION, the harassment seems to be based upon the idea that you don't belong in the neighborhood in which you live, which could also constitute a violation of the Fair Housing Act.

Now, these cases are fact specific, so I have no idea if you have a good case or a bad case, but you have enough that calling attorneys (personal injury or civil rights attorneys) and discussing the matter with them is a good idea.

While I am an attorney with over fifteen years of experience, until we sign a retainer agreement, I am not YOUR attorney. My postings are meant for informational purposes only, and DO NOT constitute legal advice, nor do they create an attorney-client relationship between us. As such, the question, my answer, and any comments left to my answer, are not protected by attorney-client privilege. Also, keep in mind that all legal claims have relevant statute of limitations, some of which can be very short. So, if you believe you need to hire an attorney, and need legal advice, seek out legal representation as soon as possible.
