I would listen to calming music and try to keep calm. They are equipped with high tech gear and have some worry to get killed but not much.
I think calming down and doing something productive like walking out in the park or reading a book is good enough. If someone you know is in law enforcement then it is obvious that they are already trained for stressful situations. If I were in a relationship with someone who is in law enforcement I would be prepared for the worst. It is easy to worry but you cannot let that bother you too much since you do not need the added stress. Stress would kill you quick so it is something that would have to be balanced carefully.
