When I goto my local Headshop I park 5 blocks away and walk there. Cops sit across the street all the time just chilling and staring at the place. 3 Of my friends growing up (all brothers) became cops like there Dad was. They were also some of the coolest herb smokers, I actually first smoked with the eldest brother who has been a cop for around 7 years now and got shot in the head in the line of duty and lived to tell about it(and is STILL a cop, decorated now to). There will be ignorant assholes in every profession and sadly Pot is still illegal so they have to do there job.
