It's a trap to arrest people for being racist against pajeets.
Caller "hello...there is a indian man taking a dump on the street. 5th and 12th"
Dispatch "we see it on survellience camera...sending a unit"
Caller "if you can see it on survellience camera why did I have to call you?
...later...
Police "did you call this in?"
Caller "yes"
Police "you're under arrest for racism"
Caller "but I reported it because the sign said to"
Police "you said "indian". You are obviously racist and need mandatory education to deal with your racism"
Caller "but he is an indian from India! that is the correct term for his race"
Police "when was your last documented struggle session?"
