Well, my gut reaction is to say no because I have never heard it used that way. I have only heard or used it to mean "to conspire to do something illegal or immoral". However, when I searched OneLook and clicked on the Collins link, I found that the first definition given is the one I am familiar with but it is followed by a second definition: "to give assent or encouragement (to the commission of a wrong)" when it is followed by "at", which fits the construction of your sentence. However, it is marked in Collins as "law" so I would only expect to hear it used in a legal situation.
