This raises the question: What is likely to happen to evidence that is not related to the Romney investigation?
Would it be returned to the owner intact? Can seized evidence be kept indefinitely?
I know in the UK if property is seized as evidence then charges dropped you have a certain time within which you may reclaim them - otherwise they are destroyed. With all the additional protections of freedoms provided by the US constitution I can't see that the rights of the wrongly accused in this respect would be
less than here.
