1st - we all should remember why they are doing this, under the old system a bomb could be put in checked luggage and it would not be detected because no screening was done of checked luggage. Now, they will xray checked luggage, to make sure that doesn't happen. I feel it is no different than standing in longer lines after 9/11, it is what is needed to be as safe as possible. I will adjust my packing habits though, putting everything in the ziplocs and space bags, making it easier for them to repack if they have to search it. If I pack in those and squeeze the air out, I don't have to worry about them repacking and wrinkling things.
2nd - I saw on 60 minutes I believe in the last few days that they recommended the cable ties. My only question is this, you cannot carry anything sharp to cut them off in your carryon luggage, I even think that includes nail clippers, so how do you get them off when you get to your destination? Most hotel rooms don't have sissors!
