What if you have a red hat?

According to claims in the media, for instance Computer Sweden, there are strong reasons to believe that Försvarets Radioanstalt, FRA, already engaged in wiretapping of phone calls, despite the fact that there is no legal support for doing so. It is said that FRA already listens, or have listened, to phone calls transmitted wireless. That may include calls over the wired telecom network which may sometimes be routed over satellite or radio, and are thus possible to listen in on via radio recievers. Although this has not explicitly been illegal according to Swedish law, it has neither been explicitly permitted. According to FRA's former second in command, Anders Wik, The European Convention on human rights is interpreted such as wiretapping is illegal unless explicitly permitted by national law. Anders Wik is said to have commented the bill as "the task" (to listen in on conversations over radio) "have existed earlier, but will now be made legal.". Thus, there are strong reasons to believe that the FRA has engaged in wiretapping whose legality may be questioned. Will the Minister take any steps to investigate to what extent this has been done?
