Apparently, the wireless radio system that police use in the UK is quite expensive. This isn't all that surprising, since such networks need much greater reliability that traditional mobile networks, but with UK police forces having a capped deal where prices go up even higher after a certain amount is used, apparently police are instructing cops to make use of text messaging as an alternative to keep their radio usage down. While I definitely understand why the police network would be more expensive, and can see some benefits to police texting when appropriate, it does seem a bit bizarre to warn police to be cost conscious in their communicating with fellow police.
