have a safety defect that if it manifests itself can cause a severe injury and yet you can't do anything about it short of parking your car and waiting for parts availability. >> reporter: takata said new air bags will eventually be available but the wait could be long because of a shortages of replacement bags and it could take years to replace all the defective units. so who's getting priority?

than subsidiaries. but scott, because of agreements made with regulators all of the banks will continue to operate normally despite their guilty pleas. >> pelley: more felonies on the rap sheet of wall street. jeff, thanks very much. there is a serious threat to the world's heritage tonight. i.s.i.s. has taken the famed syrian city of palmyra. the city mentioned in the old testament is the home of priceless ruins. the extremists of isis have destroyed monuments elsewhere, declaring them un-islamic. the fall of palmyra comes days after i.s.i.s. overran the strategic iraqi city of ramadi the

seal team 6 were declassified. and here's mark phillips. >> reporter: osama bin laden may not have had a real bookshelf in the pakistani hideout where he was killed but he did have an extensive library. he had digitized copies of books, many of them in english on computer drives along with thousands of internal al qaeda memos, all taking a dark view and many showing a hostile intent toward his sworn american enemy. some of what he read you might expect to find. the "9/11 commission final report," whose accuracy he would have been able to judge. among the files, memos to his followers saying "the focus should be on killing and fighting the american people not attacking arab regimes." but bin laden's choice in books was like a window into his world view. books like "american strategic blunders." the hint is in the title. a catalog of where the author thought u.s. policy went wrong from pearl harbor through the cold war. or, "bloodlines of the illuminati," a conspiratorial bible which claims a secret american elite controls everything from finance to war. and "imperial hubris," which argues that bin laden was misunderstood, he didn't hate the u.s. for what it is, but for what he thought it had done to the islamic world. bin laden reading about bin laden. and, scott, also among the files was an al qaeda job application. among the questions: "do you wish to execute a suicide operation and who shall we contact in case you become a martyr, write clearly and legibly," it says. >> pelley: mark phillips reporting tonight from the london news room. mark, thank you.

had been beaten or stabbed. wyatt andrews reports police are now zeroing in on a motive. >> reporter: sources say, last thursday, an assistant to washington businessman sawas savopoulous delivered a package of $40,000 in cash to his home instructions to leave the package outside. investigators are looking into the possibility the money was an extortion payment savopoulous had to pay to stop the

inside ordered a domino's pizza with an instruction to leave it outside. savopoulous and wife amy took steps through voicemail and text messages to warn a second housekeeper nelizta gutierez not to come to work thursday. >> sometimes you never understand, you know, all these things happen. but i'm lucky that i'm still here. >> reporter: savopoulous was the respected c.e.o. of a high-tech steel
