TL;DR: If the public could give anonymous tips, the drug cartels would be weakened.
If you have a hammer, everything looks like a nail. Is it really hard to give anonymous tips? I doubt it. I think the fundamental problem with informants is that only so many people have insider information on criminal activity, and there's a good chance the cartels will find their moles, even if the tips are truly anonymous.
