Is vandalism protected by the First Amendment?

Is flag burning still protected under the First Amendment in this case?

American flags, lining the lawn of the mother- and father-in-law of fallen U.S. Army Pfc. Timothy Hines Jr., were heaped in a pile early Saturday and burned under a car parked in front of the home - less than 24 hours after Hines was buried in Cincinnati's Spring Grove Cemetery.

Jim Wessel, Hines' father-in-law, said he thinks that the fire was a random act of vandalism.

The flames totaled Sara Wessel's car.
