How long did the police spend investigating Trayvon Martin?

Did the Trayvon Martin investigation run its course too quickly?  This seems to be one of the biggest issues that protestors return to again and again, the fact that it only took seven hours and 50 minutes for Sanford police and the state attorney to decide to let George Zimmerman to go home, not charging him with the shooting death of Trayvon Martin.

 

According to MSNBC, nearby Lake Mary is a similar town with the same number of detectives (five).  Two years ago a shooting happened in Lake Mary and although eventually no charges were filed that city’s homicide unit called in the county sheriff’s department with its fully staffed crime lab to assist.  That investigation lasted for 16 days. 

 

Was seven hours too quick of an investigation?  Kendall Kendall Coffey, former United States Attorney thinks so.  “When a man with a gun kills someone who is unarmed, certainly should take a lot more than seven hours to reach the bottom line as to whether there's a crime,” he explains.

                                                                                                                                    

The special prosecutor examining the case will be the one to determine the truth of the matter, and is expected to report to the grand jury soon.
