If you feel you need to do something people consider rude for the sake of your art, you can do it and suffer the consequences.  Those consequences should certainly not extend to physical violence, should not extend to the involvement of law enforcement.<p>You should be able to mitigate those consequences somewhat by treating your subjects like people - explaining what you&#x27;re doing, engaging with them respectfully.  They may still feel uncomfortable.<p>In this case, the person complaining felt violated, and that&#x27;s not unreasonable.  She is plenty within her rights to complain.
