Never knew this existed. Would it be used in chases? Whats the purpose?

Seems like a way to alert a large area of people of something, especially where police cars can't go.

That is definitely something I have never seen before.

This is the Skyway Patrol, pull over and land on the right side of the helipad!

I didn't hear any sirens.

​Your kidding right? I and everyone else clearly heard it, it's even stated in the video info.
Speakers not working?

...Nope. Didn't hear a single siren the entirety of the video; and my speakers seem to be working optimally. Is it a long stretched out tone? I'm not even sure what I'm actually listening for, does it sound like a regular siren?

Seems like a waste of money/time to me, to say the least. Helicopters that follow people are supposed to be somewhat ambiguous as to what they're doing since they should be flying high in elevation. It's not exactly safe to fly 20 feet off the ground, chasing people who may or may not be armed while trying to blast a standard issue police siren strapped to a loud helicopter burning loads of aviation fuel just over the heads of people on a crowded highway.

*EDIT* Pull over: Sky police!
