challan?
but police cant challan except for ITP n ITP dont take bribe as they already get 35% of the challan amount
n for factory fitted glasses like in JDM cars,they cant stop u,just tell them to remove the paper n when they cant they'll tell u to go 
i never paid bribe to any1,i thought if they want to remove let them but i wont give them a penny + there are so many check posts,to how many of them r u gonna pay 100 each 
oh n as for light tints,once i saw a corolla stopped at G11 check post from kashmir highway,he was removing the tint,n that was hardly even 0 %
