Yes, we searched very carefully...
...(or couldn't have searched very carefully since it's a positively gigantic country, depending on who you listen to and what they are trying to apologize for), for WMD systems that some folks thought were there. I have never heard a word that we examined the contents of incinerators used in the 90s (if they even still exist). Or that we scoured the world for the scrap metal from the rounds.
