I've been saying this for years. I routinely just stick my toiletries in my pockets to avoid having to do that stupid little baggie. I used to fly a pretty decent amount (50k miles per year) and never once had a problem that way.

Also, I messed around with cheap homemade plastic explosives in high school enough to know that the amount you could legitimately stick in plastic tubes and then cram into a ziploc bag is more than enough to cause some serious damage.

Luckily we're all safe because very few people actually want to kill a plane full of strangers, and even fewer want to kill themselves too.
