(CNN) -- Florida neighborhood watch volunteer George Zimmerman has been charged with second-degree murder in the death of 17-year-old Trayvon Martin and is in custody, a special prosecutor announced Wednesday.

Zimmerman, 28, was arrested on a warrant and was in the custody of the Florida Department of Law Enforcement, his new attorney, Mark O'Mara, told CNN legal analyst Mark NeJame.

As many of us know, there has been a lot of spirited debate from both sides concerning this event ever since Trayvon martin was shot walking to his father's girlfriend's house by Neighborhood Watch volunteer George ZImmerman. The latter demanded that he shot the 17 year old dead in self defence, claiming the 'stand your ground' law in Florida permitted him to do so for fear of his safety and life. However, that claim was quickly discounted when it became clear Zimmerman stalked Martin, further exiting his vehicle to approach Martin on foot. (the claim of self defence can not stand given the fact it was Zimmerman's actions which propelled the situation to the point where a firearm was drawn)

Is Zimmerman guilty of 2nd degree murder? That is unknown and will remain so until the case is heard before a court. Personally, I predict one of two potential endings to this story: 1) there will not be enough evidence to support a 2nd degree murder charge and Zimmerman will be acquitted, or 2) Zimmerman will agree to the lesser charge of manslaughter and face prison time anywhere form 5-15 years.

So now that he has been arrested and that charges have, indeed, been placed against him, van we stop the insanity of demanding that Zimmerman is completely innocent in this and that Martin was "just a thug"?

As I have said since day one, this will be a case of "why".

* Why did Zimmerman ignore 911 operator instructions and choose to follow Martin?

* Why did Zimmerman not announce his presence or intentions to Martin as he followed him?

* Why did he get out of his vehicle and approach Martin, again without voluntarily making his presence or intention known?

* Why, exactly, did Zimmerman draw his weapon and use lethal force?

These are the questions Zimmerman and his attorney will have to answer. His fate will be determined by the answers to these questions and the merit therein. Still, the case of 'acting in self defence' will be increasingly difficult to prove given the questions above.

I am sure more iReporters will post as information becomes more available. For now, we wait...
