Are we worried about the civil rights of a criminal in the DR? Following a thwarted attack anyone with sense is going to go. You wait around for the police? Make sure your attacker is ok? Empty the canniser and leave. If you are going to rely on the spray I would buy two or three cans and practice a bit. Might be difficult to find a friend willing to be a test dummy, especially after the first spray. Watch out for a head wind as it will blow the spray right back on you. Most people only spray into the wind one time. Has anyone ever used the spray in an enclosed space?
