How come the Police don't use hands-free kits?

Why does the policeman currently blocking the way to Charlotte Road still have to hold his radio to his ear?

from my understanding its a digital encrypted system that also randomly changes frequencies during transmissions to try to avoid decoding. But i have heard that this means that another officer cannot join a conversation and if a receiving party suffers interference along the way they loose what frequency the transmission is on and get cut off completley. sounds like a load of pish to me.

I should think the frequency hopping is to prevent jamming, not decryption...

fair enough, sounds right. apparently what they did was add in a control channel that broadcasts what is on what channel at any time... whoch kind of defeats the object.
