The internet’s speed means a rumor can outpace the law before anyone even checks it, so cops sometimes treat a tweet as a suspect’s alibi because it’s trending. That’s the problem: speed buys credulity. It doesn’t give you a hard fact, just a fast‑moving noise floor. You still have to sift the noise, verify the source, and weigh it against solid evidence. If you let the velocity of memes dictate the weight of testimony, you’ll end up convicting the wrong guy faster than you can even notice the error. The speed should make us suspicious, not trusting.
