During a news conference on Monday, Bowser asked that people stay away from downtown D.C., and avoid confrontations with anyone who is “looking for a fight.” But, she warned, “we will not allow people to incite violence, intimidate our residents or cause destruction in our city.”

There will be about 115 Guard troops on duty at any one time in the city, said the defense official, who provided details on condition of anonymity to discuss internal deliberations. The official said Guard members will be used to set up traffic control points around the city and to stand with district police officers at all the city’s Metro stops. Acting Police Chief Robert Contee said Guard troops will also be used for some crowd management.

“Some of our intelligence certainly suggests there will be increased crowd sizes,” said Contee, adding, “There are people intent on coming to our city armed.”
