I'm goin' down's POV here seems to be a general lawyers POV. We have to ask whether this is a Financial, Legal, Copyright, Patent, etc.. type of lawyer. Your speciality indication would be appreciated.
As a lawyer I'm sure you are aware of international agreements, most of which
do not agree with the USA.
If the 'offendant' resides within the USA you have a case, otherwise it might be difficult, unless the offendant resides in the puppet state 'UK'

Then this person may be extradited for making the Pentagon/DOD look stupid, as they aways are

Sorry just a good joke
