We will see more and more of this occuring. for those who know how this tech works, the very desing of public ledger/blockchain tech is designed to be transparent. Forensic investigators have a great starting point in my view, now it gets tricky when btc is pushed through exchanges and traded for say "privacey coins". But I feel with the advancement of reglation into the space we will see a tightening of AML/KYC requirments in the exchange space. The tech is great, but the masses wont come untill regulation ensues.
