Yes, any reasonable person would conclude that Kenneth Wheelers' posts were true threats. The Law Enforcement also makes use of social media in order to detect and prosecute the criminals that they are able to locate. The law enforcement officers also use various social media outlets in order to determine the location of certain suspects and in some cases, in order to determine or verify a suspect/criminal's identity.
In this case, Kenneth Wheeler believed that he was being set-up by police officers in Grand Junction, Colorado and that the driving-under-the-influence arrest was unjust. Wheeler then posted all of the mentioned statements on his Facebook page. When a prosecuting court has to determine if a 'true' threat has actually been made, they ask whether the ones who actually heard or read the threat believe that an actual threat has been made. The exhortations made by Wheeler to a large number of unspecified individuals to commit violence amounts to a true threat, more so since any reasonable person will believe that the individuals being urged and coerced to take extremely violent action are acting on the will and orders of the threatening person or persons. As such, law enforcement officers may use Wheelers' posts in order to detect and catch any related crimes happening, and then also use the posts in order to find Wheelers' location.
