Here the police use the WhatsApp extensively. You can complain through their WhatsApp no. Helps add a lot more data even if you visit in person.
mvp As long as those conversations are searchable by Google 🙂
It is a message app 😕
mvp I know. But it’s not as secure as you think - https://nakedsecurity.sophos.com/2020/02/25/google-stops-indexing-whatsapp-chats-other-search-engines-still-at-it/
But it is the most popular app here. Even Telegram is not that popular. No snapchat either. Everyone uses it.
mvp Telegram isn’t secure either. Signal is though.
It is mainly because everyone uses it. Windows, Android, there is a good amount of security risk. Similarly or otherwise, people will use it, so Police will also have to choose it.
