I think you lack a key understanding of how factions such as the Wilde and Iseijin work. The entire idea behind such factions is that they masquerade as the military and special forces elements of their corresponding house to cause chaos and discord. What was done there was perfectly acceptable Wilde RP of undermining the house while attempting to conceal his true nature.

Unless the target is mounting nomad equipment, it's generally considered poor taste to magically know somebody has a squid inside of them.
