Is it illegal to fire somebody if they did not read the employee handbook or sign it and they then break a policy they didn't know about?

Question Details: I got pulled over by police off the clock. In the company handbook which I read after termination, it says that you have to report within 3 days of any citation. I never got a ticket that night but 3 months later I got something in the mail saying that my driver's license was suspended. I gave that to them next day but was fired the same day. However, 2 other guys went through same thing and still work there. I never signed a handbook or even knew about policies regarding this and neither did supervisor when he found out. I later found out they have an "at will" clause but didn't know about that either. I was never discussed or signed anything of the sort.
