Off course the chief was pissed. Your from northern lake county (worse yet Hammond I think) and they don't want your kind (anyone north of US-30 especially punks from ec/Hammond or gary) SOUTH of US-30 period!
Your encounter would have been worse had you been of the darker skin.
It seem to be a lake county thing. The Hammond chief won't sign form 4's for silencers, machine guns, etc unless he knows you or your older then 50, so most guys have to go the Trust route! I have heard of harassment from Hammond Munster, and St. John for OC-ing. They are outta control!
