It's not one incident that makes it scary. Its the fact that the FBI thinks its okay to continuously deteriorate long-standing constitutional protections because they know it'll help them catch more criminals. You know what also catches more criminals? Collecting every single American's technology information for the purpose of back-searching it in the event of a situation. The impersonating of press (which I completely disagree with your characterization of the event) is apparently standard protocol. By giving them the ability to steal their email format and letterhead style, they essentially have the ability to impersonate the press. Granted, in the publicized case, they only used it to act as a link to a news report about the suspect they were attempting to place malware on, but I don't think it is too far-fetched to see this line continuously move closer towards impersonation and further away from the clearly legal line.
