Once I'm off the clock, sure. We actually discussed this in training, what one does if one discovers evidence of a crime while on the job. Violent crime, with imminent danger to someone, I call 911 immediately. Non-violent crime, such as immigration issues (which I'm actually pretty unlikely to discover anything actionable on while I'm working), my orders are to complete my work for the day, clock out, and then make whatever anonymous phone reports I feel compelled to make. What I cannot do is report it in my official capacity as a Census Bureau employee, or reveal any personal information from Census records or paperwork. What I do as a private citizen, on my own time, with my own personal information and observations, is entirely up to me.
