I refuse to accept violence as an acceptable alleviation of stress. If you wish to, so be it, but I'm sick of unnecessary violence and this is an example of it.
I'm making an assumption here, but it is one based on statistics... This older man is likely a Christian. I get annoyed when Christians choose not to follow their savior's teachings. This man could have turned the other cheek, walked into the business and called the police. His resort to violence was not made in self-defense, again, the reporter posed no physical threat... he was nothing more than a pain in the ass. The violence was exhibited for stress-relief, and that is unacceptable.
