When the special police perform their duties, are they not allowed to contact anyone except the closest family members?

Even family members are not allowed to touch each other when performing tasks. There is such a rule, but you must confirm your boyfriend's swat identity. Now some people fall in love under false identities, because it is a bit unreliable to show that they have read it. Only when performing a task can they have communication tools except when the leader or task is assigned to outreach, and no one else should have communication tools, let alone start reading it. If they can understand it, they should be able to reply.
