Is it really true that the walkie talkies that police use are on VHF and UHF frequencys?
And that police dispatch from the cop car to and from is on GPS 1 and GPS 2 frequency?

Depends on your region. It's possible. You could also just use a police scanner app if you are interested.

It is quite interesting to try one of those! ^^

This only works if you have somebody in your town broadcasting the scanner, Unless you are interested in towns other than your own. For starters I would either recommend the rtl-sdr for $10 or the baofeng UV-5R for $30. Those are probably the easy way into scanning and RF hacking/research imo.

About the walkie talkies yes. Now about the GPS, I really doubt it, GPS2 is for military use and even if police had access to it, it would probably be only US police.

I've listened to emergency radio using RTL-SDR

Problem is in my area they use channel hopping and encryption... so you need multiple RTL-SDR dongles to cope with the channel hopping, and DSD for the encryption.
There might be newer decryption software than DSD, but that's what I used a few years ago...

Fun stuff... but difficult... and half the time nothing interesting going on...

I found it more interesting to use SDR to monitor planes passing overhead using ASDB
