Honorable mention - Larry "release them all" Krasner for policy he supports and laws he ignores.
Third place - the Philly P D for sending hundreds of officers and allowing them to get that close when a smaller team up front with guys in the rear providing cover would have been wise.
Second place - The non - stop "news" coverage which provided the advantage to the shooter by showing him where the police were so he could maximize the damage as he continued to shoot, like fish in a barrel.
First place - Jim Kenney for saying that this is a reason for new gun laws. Hey genius, this bad hombre has had many gun issues in the past, none of which were purchased legally.
Got any other "winners" for us to consider?
