Being charged as an adult

I recently wrote a commentary, published in the Baltimore edition of the AFRO American Newspapers, entitled "Calling It For The Cop." This was my reaction to the police shooting of a 14-year-old suspect during the course of a robbery in Baltimore.
According to the Baltimore City Police spokesperson, the officer came up on a robbery in progress, where the suspect was pointing a gun at the neck of his victim and did not comply with the officer's instruction to put it down. It was only afterward that the age of the suspect was known and the weapon identified as a BB gun.
I wrote -- and have heard no facts to change this opinion -- that I believe this to be good police work and that a plausible consequence of pointing a weapon is to be shot by the police. I added that at 14 years old, the suspect was able to form the intent to carry out his actions and knows right from wrong.
What I did not add is that at 14 years old, he should not be tried as an adult.
