However, if a highly trained drug dog alerts at the outside of a vehicle, would a reasonable person conclude drugs are inside?

Let's say I train my dog to always "alert", now what? Prove you're innocent, that's what.

The article is quite clear that accuracy results aren't necessary: "the Florida Supreme Court, in the 2011 decision that the U.S. Supreme Court overturned, said police should provide information about a dog's hits and misses."

“Let’s say I train my dog to always “alert”, now what? Prove you’re innocent, that’s what. “

You are never convicted based on a drug dog. The only effect of the drug dog is to give reasonable cause to conduct a search, with the possibility still existing that any evidence found will be thrown out of court.
