Dog detectives behind the headlines

This week Steve Walters takes a look at the use of sniffer dogs in crime detection

SNIFFER DOGS are used by police and customs officers all over the world to detect drugs and explosives. Dogs have a far better sense of smell than people because their smell receptors at the top of a dog’s nose are 100 times longer than in humans

Training for a sniffer dog lasts 12 weeks. They are trained in two stages. First, the trainer teaches the dog to recognize a particular drug or explosive. He hides a sample of the drug or explosive inside a rolled-up newspaper or a rag, which is called a training aid. He places it where the dog can see it and tells the dog to bring the aid back. When it does so, he gives the dog a reward – usually a friendly fight with a trainer or a bone.

The dog soon learns to recognize the substance by its smell. The type of training aid is changed regularly but the smell always remains the same. In the second stage, the aid is hidden where the dog cannot see it. Smells such as perfumes, which some smugglers use to hide the smell of the drugs, are also used so that the dog becomes familiar with them.

Sniffer dogs are trained to detect 12 different types of explosives and four different types of drugs

Fay Rowan interviews Errol Mason, a young police officer from Bristol

When I contacted Police Constable Errol Mason, he was just finishing a nine-day night shift and was understandably trying to catch up on lost sleep. “It’s hard to sleep during the day but you just have to try,” said Errol, “otherwise you end up exhausted.”

I asked him when we could meet for a chat. “What about coming along to an ice rink on Tuesday evening – say, about eight?” he suggested. Errol told me that he spent most of his free time playing ice hockey. So the following Tuesday evening I sat and watched Errol skating across the ice. Later, over a cup of coffee, I asked him what his job in the police involved. “Many people have only one image of the police. They think we spend our time chasing criminals in fast cars with wailing sirens and flashing lights,” said Errol with a grin. “In fact, that’s only one small part of the job. A lot of police work can be quite boring. You can be on the desk doing routine office work for a whole month at a time. Then the next month you may be driving around on patrol. Then, perhaps, you’re ‘on the beat” for a bit”

Errol told me that one of the most interesting parts of the job was in fact “community policing” I asked him what this involved. “You have your own special area which you have to patrol. It really means being on the beat: walking round keeping your eyes open, making sure you know what’s going on, chatting to people, basically trying to prevent crime”

Thinking of some of the recent ugly scenes at football matches and demonstrations, I asked Errol if he was conscious of the dangers involved and if he was ever frightened. “Sometimes, yes,” he replied. “Anyone would be. It’s just one of the things you learn to accept. Violence is always frightening and a lot more people nowadays are carrying weapons- knives, cashes and so on. Except in extreme circumstances, all we carry are truncheons, handcuffs and a radio.” When I asked if the irregular hours of police work affected his social life, Errol smiled. “My girlfriend gets a bit annoyed- she says I’m either on night shift or I’m playing ice hockey! But it’s not like being a doctor. When you are off duty, that’s it. It has to be a real emergency like a major riot or something to be called out on your night off.”
