I'm very interested to hear how responsive the police have been. I have been on the receiving end of similar abuse and it never occurred to me to call the police, even though I could identify the perpetrators by licence plate or where they live (such as the lovely lady who threatened to kill me for parking perfectly legally outside her house and got her dad and brother to come out and have a go too).

Knowing that the police will be supportive makes me much more likely to call them in future. So thanks for that, Londondrz.
