Cops need a reasonable suspicion to search your vehicle or belongings.

And an easy way of claiming they have one is having dogs point at things, usually on command. It's a legal loophole.

Other tricks include claiming you have a slurred speech, or that they smelled alcohol breath or marijuana.

Then they can search your stuff, find nothing and say it's a false positive.

Having dogs point at things is already (or should be) "search".

In many states, a dog indicating is used as the threshold of probable cause.
