Halloween is an exciting time of the year. Everyone is encouraged to dress up and become someone or something he or she is not. While Halloween is an excuse to be something different than normal, it's not an excuse to be offensive and insensitive as these cringe-worthy costume creators discovered.

Sticking with national news references, the above duo (William Filene and Greg Cimeno) went as Trayvon Martin and George Zimmerman.
