Nor would I. If they were tasked with decryption of this woman's hard drive I'm betting the NSA has systems that could, by brute force alone, easily break through whatever 128 bit encryption she used.
Perhaps, there is an (yet unknown) attack that could be used that would "break" the encryption in less time then a brute forcing, say the entire AES256 keyspace, but it would probably still take years.
The longest The largest successful publicly-known brute force attack against any block-cipher encryption was been against a 64-bit RC5 key by distributed.net, and took 1,757 days, 58,747,597,657 work units and about 330,000 GPU equipped PC's.
