Handheld flamethrower
From Wiki 24
The terrorists in Day 5 used a handheld flamethrower in order to attack the motorcade of Russian President Yuri Suvarov between 4:00pm-5:00pm
California has restrictions on private ownership of flamethrowers. The production created one with a propane tank so that effect gave off a flame stream without the spray, splatter and smoke produced by the authentic weapon.
