Yes the information is public but if the routing information exchanged over
a given peering session is tempered with that could potentially cause some
problems right?

But then again, as Jeff mentioned, with GTSM this vector is limited to a
local link between two eBGP speakers (or whole IGP domain for iBGP sessions
but let's leave that one out for now).
So move from bilateral peering over common IX-LAN to direct peering 
Or if a direct link is still not to be trusted do MACSEC.
Then it's all about you and the peer -if he/she screws you over de-peer.
