That's ######. It's people on fast-track degree management schemes that don't go on the streets as a PC who are the reason for the cutting back of police dogs. They're brilliant, you obviously have not worked with them.
You have 20 people outside a pub and two police officers to deal with a few people kicking off and drunk. Bring one police dog and open the van - the dog is barking. 10 people disperse from the scene in fear of the dog. The dog is taken out of the van, another 5 disperse - now the situation is much easier to deal with all thanks to a police dog.
Police dogs have found massive amounts of money, drugs, human remains and many other things that frontline cops would not have a chance of finding.
