Maybe you can get away with giving a fake name to the cops for a little while, but in this day and age, not for long. Although in this case, technology was not even a factor. From the Murfreesboro (Tennessee) Post:
When most people get pulled over by Murfreesboro’s finest and are asked to produce identification, they do so willingly.
But David Prochaska, 21, of Tomahawk Trace, thought differently when he was pulled over Wednesday and claimed to not have an ID on his person. He also gave a fake name and social security number.
That’s not the only difference between Prochaska and most people. He also has his initials tattooed on his neck.
After noticing D.J.P. on the suspects neck, Murfreesboro Police Officer Ramona Thomas, searched Prochaska only to find a receipt in his pocket with his real name on it.
“It was also determined that Mr. Prochaska had four active warrants of his arrest,” Thomas reported.
