Yes it does. Incidental means I was collecting the data for purpose A and then misusing for purpose B.
I dont expect you to understand/agree but others will see this as the formation of a GENERAL WARRANT.
You're quite wrong.
"Incidental" in this context refers to information gathered on Person B, as a result of that person being in contact with Person A, for whom the warrant was issued.
For example, suppose the FBI has a warrant to monitor Al Capone, and Bugsy Malone calls Mr. Capone to plan a bank robbery (or Capone calls Malone -- in the sense of "incidental information," there's no difference).
The warrant is for Capone; and the information concerning Malone is "incidental" to that warrant; however, it is also evidence of criminal intent by Mr. Malone and as such, by law, the FBI must report that incidental information.
