Lex, the drug-sniffing dog, has been a very bad boy. No, Lex didn't bite anyone. He never peed on the carpet or tore apart an officer's shoe. Rather, Lex sniffed drugs on just about everyone he encountered -- whether there were drugs present or not.
Lex's nose was just about as accurate as a coin toss, according to the Seventh Circuit. Lex's poor drug-sniffing skills weren't bad enough to remove probable cause, however. Lex's shortcomings did allow the court, in an opinion released Tuesday, to highlight the risk of police using inaccurate dogs as a pretext for otherwise unconstitutional searches.
