Police in Dortmund who tried to stop a knife attack against a 15 year old found themselves surrounded and threatened by a crowd.
In a similar incident in Berlin, migrants threatened to mass together to shoot police officers called to the scene of a crime.
The growing number of attacks against police are an ominous warning of what could happen if Germans do not start mass deportations soon.
Once the police become a target of migrant attacks, and are conceivably even shot in large numbers, no German citizen will be safe.
