Park police disturbs me

[Cataboo]

Would it be all that much safer if a police officer drove his car behind a peleton with his siren blaring & lights flashing and followed them till they stopped?

I know loud sounds can momentarily freak me out when I'm riding and if I was going 30 mph down a hill, I'd like to say I'd recover before I crashed... but I'm not riding in peletons or a tight formation... Just tottering around at my speed, if I look away for a second or so I can sometimes hit a pothole or grate in the road.
