Get ready for even greater security measures in October:

Convinced that al Qaeda is still determined to disrupt the U.S. fall elections by an attack on the homeland, FBI officials here are preparing a massive counter-offensive of interrogations, surveillance and possible detentions they hope will disrupt the terrorist plans, reports CBS News Correspondent Jim Stewart. FBI field offices and Homeland Security agencies will be advised of "extraordinary measures" that will go into place "beginning the first week of October through the elections."

...Specifically, the plan calls for "aggressive - even obvious - surveillance" techniques to be used on a short list of people suspected of being terrorist sympathizers, but who have not committed a crime. Other "persons of interest," including their family members, may also be brought in for questioning, one source said.

All recent truck thefts, chemical thefts and suspicious cargo truck rentals will also be reviewed as part of the plan. Mosques will be revisited and members asked whether they've observed any suspicious behavior.
