Sometimes people need to vent. An internet forum is an easy place to blow off some steam and maybe get some support from people going through the same thing. A post here and there might not change the situation, but it might make someone feel better about it. No big deal in my book.
The original PCCs (the passport office one and the local police stattion one if your passport has been issued >6 months ago) would have been sent to the NVC in the ds-230 package. So you wouldnt have the originals anyway; they would already have it at the embassy. for the day of the interview, you should definitely have made copies of ALL materials you sent to the NVC, and so thus you should make photocopies of the PCCs before you send them to the NVC in your ds-230 package. one trick that I used is to scan every piece of document as jpeg or pdfs and store in your gmail (google docs) or yahoo email account. that way even if you lose your copy somewhere, it is always there electronically. obviously you should also save the files in some sort of hard drive or a flash drive, so you can just print things out should you lose the physical hard copy. good luck!
btw, PCC requirements for mumbai consulate are here - http://mumbai.usconsulate.gov/ivpolicecertificates.html - review them carefully - you may only need 1 PCC if your passport was issued within the last 6 months.
