Two dead as gunfire erupts at Wisconsin protests over shooting of Black man

'KEEP HIM ALIVE'

"Stay down, stay down!" someone yelled.

Another social media video shows a man with a severe arm wound sitting on the ground tended to by a man with a long gun as police approach.

Yet another video shows a man lying between parked cars with an apparent gunshot wound to the head. Several people rushed to his aid.

One bystander took off his shirt to stop the bleeding, but had trouble finding the wound, until other people came to help.

"Put pressure, put pressure," one person said.

"You shot him?" someone asked.

"I didn't," came the response.

Others implored the wounded man to keep his eyes open and told him he would be OK.

"You've got to keep him alive," someone said.

Before the gunfire, police in riot gear fired rubber bullets, tear gas and flash-bang rounds to push back demonstrators who defied a dawn-to-dusk curfew and gathered outside a courthouse and adjacent park.
