Why 'are', Maaarysia? The police is a collective unit, right? It's one group, no? It's a singular entity in the eyes of people, true?
Yes but I can swear that I've seen it somewhere as a tricky mistake. In Polish it's
policja jest so you wouldn't ask me if there was no catch ;)
You had already written that sentence when It'sallaboutMe asked you. The action is finished and the time is finished so it's past simple.
But the result of the sentence is still visible and we're disccussing it... I will never get it when we use present perfect :(
