Do you think that riots and property damage, and poor business owner's stop when the sun goes down ? Yes those who are true peaceful protestors go home before dark probably, but that's not where it all stops. The real crimes begin after dark usually... The citizen's attempting to protect their properties from the criminals who were intent on looting, burning, and destroying their property during the night is part of the night life also. Crime is crime, and when the law broke down, the citizen's have to become law and order or we end up with total chaos, murder and mayhem in this country. Individual stands must be taken when law and order break's down in society. That won't change whether it's black communities being burned or white communities being burned. When law and order break's down due to corrupt politician's or a corrupt government, then the citizen formed militia's must then come into play, and they must restore law and order if the law has broken down. That's just a fact.
I think the police should arrest vandals, arsonists and looters.
