Here is an easy to read text about how soap works. You can also read a little about why FDA does not recommend using antibacterial soaps here.

Several articles present studies that conclude that the antimicrobial soap they have tested, is not more effective than regular soap. This one, for instance.

I took part in an exercise like this myself at my university, where the antibacterial soap actually removed less bacteria than any other soap tested. Even less than the normal soap of the same brand as the antibacterial one.

The point is to wash off microorganisms, not to kill them, so antimicrobial activity is really not necessary. So in the best case scenario, you probably just pay more for nothing. Worst case, you help the organisms become resistant.

If you really need to make sure, and you want to kill any “leftovers” on your hands (like I needed to when I worked at the pathogen lab at the university), you should wash your hands with NORMAL soap and THEN use alcohol.
