I'm not even sure it's faster.

I flew out very early one morning and put my toothbrush, etc, in a small plastic bag and stuffed it into my duffel.

The scanner detected the liquid so they pulled me to the side. As soon as the TSA agent saw the bag with the toothbrush she made a "ugh" sound, had an annoyed look on her face, then closed everything back up and let me through.

Which tells me this is a very common occurrence.
