Social media used to foster violence in Baltimore riots?

Fox News:

An analysis of social media traffic in downtown Baltimore Monday has unearthed striking connections to the protests in Ferguson, Mo. last year, according to a leading data mining firm that shared its findings exclusively with Fox News.

The firm, which asked to remain anonymous because of its government work, found between 20 and 50 social media accounts in Baltimore that were also tied to the peak period of violence in Ferguson. While further analysis is being conducted on the data, it suggests the presence of "professional protesters" or anarchists taking advantage of Freddie Gray's death to incite more violence.

The use of social media to fuel violence in Baltimore has already been highlighted by law enforcement. On Monday, police said an online call was issued for a "purge" at 3 p.m. ET, starting at Mondawmin Mall and ending in the downtown area. That type of threat is based on a movie called “The Purge,” the plot of which involves rampant lawlessness.

The Washington Times also reported Monday that law enforcement intelligence officials issued a warning after someone sent a text urging people to “kill all white police officers” in reaction to Gray’s death. The text has fueled fears that the violence in Baltimore could spread nationally, according to safety memos obtained by The Washington Times.

Why are people rioting over the death of a career criminal?  It appears there are some thieves who were looking to take advantage of  people's emotional reaction to his death and the irresponsible actions of so called leaders in the community.  Do these people really reflect the attitudes of the people of Baltimore?  Baltimore is a city run and controlled by liberals for decades.  It looks like liberalism has failed again.
