Re: Ambulance

I think prisons have fixed lines, just a guess.

Prisons have fixed lines and the price per minute is in the pounds range (in addition to them being spied upon even if you decide to call your lawyer or MP).

So this is as less about control (so that the mafia boss cannot run his family out of jail) and more about revenue assurance. End of the day - for each mafia boss in jail there are 2000+ petty criminals which should pay their fair share to whoever HMP has a revenue sharing agreement with.
