Fingerprint verification is a fairly common and practical technique. When the police were gathering evidence, they specifically took fingerprints. Now, as long as we verify Tiger's fingerprints, even if Tiger had a hundred mouths, he couldn't explain it away—it's like finding two identical leaves in the world, fingerprints are unique.
Tiger's face turned green. At the time, he thought he had hidden everything well, and he never took the police seriously, so he didn't wear gloves when hiding drugs and other things. His fingerprints were definitely on them, and that was conclusive evidence. Yet Tiger was still not willing to give in, and he shouted loudly, "So what if there are fingerprints? You must have gotten me drunk, then stealthily took my fingerprints."
"I have plenty of money, I can hire a top lawyer," Tiger shouted loudly.
