EVERY time I have seen a cop I haven't used the Report feature because I'm a mile away by the time I report. Then the report is inaccurate and useless for everyone else.
Make it so I can drive by the cop and then pull out my phone and place a pin on the location wjere the report should actually be. I understand your worried about people abusing and reporting thing across town so then only allow someone to report and pin drop something within 1/5mile?
