Wednesday’s fundraising visit to Denver by President Joe Biden, followed by the next night’s Global Conference for Israel, brought hundreds of protestors to downtown to decry the bombing of Palestinian civilians by Israel. Outside the Colorado Convention Center on Thursday night, and unable to get into the structure, protestors threw projectiles at police and the building, breaking a window and covering the legs of its iconic “big blue bear” sculpture (officially called “I See What You Mean,” by late Colorado artist Lawrence Argent) with spray paint, crayons, lipstick and other graffiti-media. “We don’t have a CSI crime lab in the back, but if there’s a substance on it that we can’t get off with the chemicals on hand, we call the city or the artist’s (estate) to come clean it up,” said Rich Carollo, director of sales and services at Colorado Convention Center.
