How was she even able to get a lighter on the airplane?

Just get up, rip her hood off and pummel her head till she stops...

She was clearly trying to set something alight after they grabbed her cigarette. She restruck the lighter when it was out. Handcuffs & land at the next airport, who knows what moght be in her baggage. Also put her on no-fly list.

Why isn’t someone rendering her unconscious and removing her from the plane?

Lighters have been allowed back on planes, and I'm okay with it. There will always be dumb, ignorant people who do stupid shit. Honestly, the only thing we do when we idiot proof something (in this case of the sake of "safety") is just create bigger and "better" idiots.

Smack Her With a Shoe. That’s All It Understands.

You can take lighters on the plane.

The definition of terrorist.

TSA allows “bic -type” lighters in carry-ons

Muslim, tsa can’t touch them.

He's a natural born entitled bastard
