The Constitution, through the
Fourth Amendment,
protects people from unreasonable searches and seizures by the government. The
Fourth Amendment, however, is not a guarantee against all searches and seizures, but only those that are deemed unreasonable under the law.
The "search" was legal on Kysliak, the finding was of Kysliak communication with Flynn. Unmasking was reasonable and allowed by law.
How is that not constituional under 4th Amendment??
And if it's such a clear violation of Flynn's constituional rights why is he not suing the government? Maybe you can give Flynn's lawyers a call and explain to them how to better defend their client.
I think this makes more sense: you don't know what you are talking about.
