Whitney Cummings Grabs Wooden Swords, Goes Arsonist Hunting in L.A. newsthirst.

Whitney Cummings will defend L.A. at all costs … readying for war “Game of Thrones”-style — with a wooden sword in hand, ready to do battle.

The actress and stand-up comic shared multiple clips to her Instagram Story detailing her eventful evening Thursday night … beginning when she says a friend told her people in her neighborhood caught a guy trying to set fires on a back hill — saying she thinks they caught the guy in Woodland Hills.

Cummings seems to be referring to a viral incident that’s circulating on social media … featuring residents holding down a man with a blowtorch before calling the police — though it’s unclear if this individual actually did anything Whitney’s claiming.

Fast-forward a bit, and it looks like Whitney’s decided to take matters into her own hands … leaving the house with her beau … explaining they’re going on patrol to stop alleged arsonists — and, they’ve got weapons.

Well, they’ve got objects that look like weapons at least … ’cause Whitney holds up a pair of wooden swords — and jokes they’re ready to duel anybody looking to light up the region.

Whitney says they can’t really kill any suspected firebugs … so, they gotta bring enough crazy to the situation to scare them off — hence the swords.

For how serious the L.A. fires are — they’ve already burned more than 35K acres and killed at least 10 people — these clips certainly provide some levity … with lots of laughter and jokes. It’s a sharp shift from earlier this week when Whitney bawled on video while being evacuated.

Multiple celebrities have claimed arsonists are responsible for all the fires in L.A. … though right now, only one person has been connected and accused of starting the Kenneth Fire — the other fires are not thought to be the product of arson at this time.
