Warrants are not a high a hurdle in practice when they are needed. The US has the third-party doctrine, so all information you've communicated to someone does not need a warrant unless otherwise protected. In the US you need to establish real probable cause (otherwise the fruit may be poisoned), but PC is a low legal standard. Non-US jurisdictions don't use the fruit of the poisoned tree doctrine and so the actual legal standard is more like "arguing probable cause for the warrant shouldn't look like an outright perversion of justice". The world's best limbo performer can't dance under that bar.
