Why in the hooey would you "eat" or "drink" a corrosive, knowing what it was going to do to your "insides"? The only logical explanations are:
1) he was trying to destroy evidence and didn't mind becoming a "martyr" or
2) he didn't know what it would do to him, which means he wasn't knowledgable about what he had and was transporting it for someone else.
Exactly; did he have a death wish? Swallow the evidence and die? Poor misguided chap -- and that's being nice ;).
There is something odd about offering a huge bribe to hush up a fender-bender, and even odder about an apparent suicide attempt in the wake of its refusal.
His name sounds Hindu rather than Muslim, so the authorities' dismissal of a terrorist link is plausible. OTOH I've read accounts of a resonably highly placed operative in an al Qaeda-linked Kashmiri group who was a convert from Hinduism to AQ's brand of Islam. We do have a Saudi-financed mosque here in Manhattan. . .
