Harder time for a crime I didn’t do (Part 1)

Why does it seems that cops have  nothing better to do but putting people in handcuffs? I mean, I was minding my own damn business. Why would I rob a store that I religiously go to? On top of that its not like I had motive to do so. Now I'm sitting here behind bars waiting for them to figure out who really did it. And as I wait, I'm thinking who could have known that I have been there before.
