On Overkill difficulty, they do not appear at all aside from the one or two pairs who arrive in police cars on certain heists; the Hostage Rescue Team usually arrives first, 10–20 seconds after the alarm is triggered.Note that in heists like the Jewelry Store, Mallcrasher, Ukrainian Job and GO Bank, Metropolitan Police officers can occasionally spawn outside of the main objective.
Two of the warehouse guards on Day 2 of Election Day (assuming the correct van was tagged or the entire database was retrieved on Day 1) will be Metropolitan Police as well.
Yellow SWAT units stop spawning under normal conditions once playing on Very Hard or Overkill, though they can rappel down from helicopters in a few heists..
Once the regular cops have determined that the situation is volatile enough to require specialist weapons and training, they call the SWAT, and these boys in blue are the first guys on the scene.
Street cops, like security officers, have the ability to cuff heisters.
On lower difficulty levels, street cops appear throughout the first assault wave, but are rarely present afterwards.
