A guy in my class awhile back was arrested and then later had all charges dropped. His lawyer said you won't have to worry about it showing up on your record. Well, when it came to the "have you ever been arrested question" he answered no. The company found out and kicked him out of class.
This is why this needs to change from "arrested" to "convicted". I know a few good people who were in the wrong place, at the wrong time, arrested, and either charges dropped, or found not guilty.
