That "strong oversight" has been hampered by a refusal to publish details (we have absolutely no clue why there are so many wiretaps, and it's been hard enough to get the authorities to publish the raw numbers), and the oversight fails when it comes to storing and providing access to the collected data. The latter is particularly worrying, because we already know that in other areas, police access to private data collection is seriously being abused, and very badly organized. The oversight basically starts and ends with granting the permission to wiretap. Everything else is murky as hell.
