A lot of us are trained in cop-ese. It sounds soooo much more official to say "I activated my marked vehicle's overhead-mounted emergency lighting equipment to effect an enforcement stop" instead of "I turned on my red lights and he pulled over". Once you're stopped, you exit your marked vehicle and initiate contact with the aforementoned defendant. Getting out of your car and speaking with someone just sounds, well, normal. And if you're writing a search warrant, it apparently is absolutely essential to some guys to write like a 16th century British lawyer-playwright. "Wherefore your Affiant prays the Court for issuance of a warrant...". Come on, the judge isn't going to turn you down if it says "I request that a warrant is issued.".
Be a person, not some robot who is stuck in week 1 at the academy forever.
