Fuh, I spend half of my day today at police station because some paranoid guy called the police. We had a conversation with him and I tried to explain him what I'm doing, with no success.. The area I mapped had quite a few burglaries recently. But still they arrested me with no evidence, after I explained them what and why I'm doing. Three cars, six policeman, six hours enclosed for nothing. Even better they did search at my flat as well. Did anyone experienced something similar ? BTW next time I'm going to check crime map (http://www.police.uk/) at least being in UK to avoid such an experiences.
