Dolphin Police is the most refined form of law enforcers on bikes I have seen to date in Pakistan, (achay buray log har jaga hotay hain isliye generalise kerna ghalat ho ga) but over all they always treat you with respect while (if) they are inquiring or stopping... unless you are a machar rider with no helmet and zigzaging accross the road or doing a wheelies or may be looking suspecious for any reason...
I live in lahore too... and like 3 times I happen to got engaged with them (once while over speeding on a touring bike) but they were largly polite and just checked my papers warned me that I should behave... and I accepted and then they were even more interested to learn about my bike as they had a similar machine as well...
