Poner en evidencia

Poner en evidencia
 

Como se dice en inglés poner en evidencia, es lo mismo que resaltar.

to highlight
to bring out
to emphasize
to show/prove/demonstrate

To me, "poner en evidencia" also has the connotation of embarrassing the person you are doing this to. For example:

Ella me puso en evidencia en frente de todos.
She embarrassed me in front of everyone (by sharing some secret about me).

So here's my translation:

poner en evidencia a alguien = to divulge a piece of detrimental information about someone with the intent of embarrassing them

I think it has got both meanings, you´re both right.
