If you've got a teen who's going to prom this year, you're no doubt concerned about them being on the road on a night when some high schoolers will, unfortunately, be driving under the influence -- even though they're not old enough to even legally drink. Since proms are typically on Saturday night, when most fatal accidents occur anyway, the dangers are even greater.
One of the oldest principles in criminal justice is the power of eyewitness testimony. Before forensic evidence came into its own, it was one of the only ways for victims and bystanders to identify an alleged criminal. And to this day, juries are still heavily swayed when prosecutors present witnesses claiming that the defendant was the person they saw committing the crime.
