They don’t care about the iPad or the speakers. The lighter/knife bothers me, but they see iPads and speakers all the time. There is no requirement to take those out of the bag.
They also don’t care about the camera. Another thing they don’t care about, even though they say they do, is small bottles of liquids. I have flown countless times and I NEVER put those small bottles of liquids in a see-through bag like they say. Not one time have they ever asked me to pull them out. The only thing I’ve been asked to remove was a full-size can of shaving cream that I’d forgotten about.
“There is no requirement to take those out of the bag.”
It also depends on the TSA agent. Just spoke to a few when i was bored and she was ordering coffee, that the TSA guy told me he’s new to the job and most of them do not even know some of the regulations..
I did chat to the LAPD guy right at the back of the TSA guys texting on his cellphone and laughing, he told me the same thing.
Yes, they see consumer electronics a hundred times a day and know what to look for. If they saw a strange orange silly-putty mass in one of your gizmos you can bet they’d want a closer look.
