DENVER -- The Denver police union is selling T-shirts that poke fun at protesters at last month's Democratic National Convention, but the main target isn't laughing.

The back of the shirts reads, "We get up early to beat the crowds" and "2008 DNC," and has a caricature of a police officer holding a baton.

The front has the number 68 with a slash through it, a reference to the Recreate 68 Coalition, which organized several demonstrations during the convention.

Recreate 68 organizer Glenn Spagnuolo called the shirt appalling and tasteless.

Spagnuolo released a written statement Thursday saying members of the police union "clearly have no respect for the rights guaranteed by the U.S. Constitution."

Detective Nick Rogers, a member of the Police Protective Association board, said police often issue T-shirts to commemorate big events.

Rogers said each Denver officer was given one of the shirts free and others are on sale for $10 each at police union offices.

He said the union expects to sell about 2,000 of them.
