No it doesn't. If you set up PGP or SSL you'll be able to encrypt things and might even misuse this capability for crime, but you won't have installed a platform where crime is openly advertised.

I like Telegram, a lot, but if you're ignoring the fact that large parts of it openly function as a mall for criminal services (and it's 100x easier to find that stuff than via Tor, for example) you're not being honest with yourself. A lot of people here are just reflexively assuming its mean cops vs encryption because that's an issue tehy personally care about, and ignoring any other context.
