I thought that GSM was well encrypted as it was?..

I think you should assume that most of the crypto in GSM has been broken
to a greater or lesser degree. Remember that:

(1) GSM is really quite old now, and

(2) there were political reasons to limit the strength of the crypto

I'm pretty sure that real time cryptanalysis of an GSM call was
demonstrated at one of the hacker conferences quite a number of years ago.

Well if you have ever listened to Police traffic theres not a lot of it
thats likely to give any villains any advantages and in most cases its
lost its value after a short period of time anyway and where are the
devices that are generally available for interception anyway?.

You'd need something a sight more sophisticated than a hand held
scanner;!...
