Wisconsin Gov. Tony Evers is deploying 500 National Guard troops to Kenosha in anticipation of unrest as prosecutors announce whether there will be charges in the shooting of Jacob Blake.

City workers on Monday finished installing security fencing around the Kenosha Courthouse and cops closed off side streets in anticipation of protests, Kenosha News said.

City police said in a statement Sunday that the measures were among the “planned precautionary efforts to ensure safety.”

County officials also offered to assist the city if necessary, Kenosha County Executive Jim Kreuser said in a statement Monday.
