How many of you think he should be allowed to walk free because of his beating?
The armed robber was not beaten, he was subdued. And even if the employees committed some crime in subduing him (IANAL, but I can't see anything I would consider a crime) then they should be facing charges of their own. The perpetrator is still an armed robber and needs to be prosecuted on that basis.
People on twitter are demanding the employees be arrested and the robber released
Examples? Not disagreeing they exist, just want something to laugh at.
