Poland's democracy defenders in Brussels turned out to be EU employees.

The burden of proof is on the accuser. Innocent until proven guilty.
I said 2 pages ago, the journalist should post some photos, label the supposed EU employees, list the bureaucrats by name. She did none of that. All she said was "there are many... among them". Many ? How many ? Is 5 among 30 people many ? Is it 20 among 30 ?

We'll never know.

Basically just insinuations that she wouldn't (or couldn't) back up.
