Many airsoft guns look very real, take the orange marker off and most would believe it was real.
http://www.nbcnews.com/news/us-news/tamir-rice-shooting-cleveland-police-under-investigation-n254716Police said officers responded to a report of a person waving a gun around at a playground and that Tamir was shot after he allegedly refused to put his hands up and reached in his waistband for what appeared to be a handgun. The handgun turned out to be an "airsoft" replica toy gun, which shoots pellets in a similar way that a BB gun does. Cleveland police said in a statement that an orange marking designed to make the toys distinguishable from real firearms had been removed.
A man who called 911 told dispatchers the boy was on a swing set and pointing a pistol that was "probably fake" and scaring everyone � but officers weren't told the caller thought the gun might not be real, the president of the Cleveland Police Patrolmen's Association told The Associated Press.
