they ask why you were speeding to get a confession from you for the record.
Why do they say its just a random breath test when they chuck a U turn from stationary, weave inbetween traffic for 5ks to get behind you and pull you over. Sometimes i think i should just pull over straight away when i see a cop chuck a Uturn and just wait for them.
Im all for the cops doing their job and enforcing the law so I really dont have worthwhile questions to ask, just annoyed at the unofficial targeting. That speeding question by ANTGTR is good.
