If you ever attend a police funeral, police memorial day service, or are around a bunch of cops after one is severely injured, heaven forbid, brace yourself. You will see the two cops that you know are roughest and maybe even jaded, hug each other. Don't let this shock you.
The longer you work in this vocation you will notice there will be a bond that develops. When you work with a squad so long, go through thick and thin together, there is a bond there, very similar to those who have served in combat together.
You become brothers and sisters to each other. Strangely enough, I have seen some bonds as close as if not closer than blood family. I still have a few "brothers from a different womb" who are extremely close to me. Yes, when I see them, we hug.
It often takes a major or emotional event to remove our mental armor but it happens. Any Police Memorial Day observance will rekindle memories of brothers and sisters we lost. Yes, real cops cry. Yes, real cops hold onto each other. No, you are not losing your mind seeing this.
Yes, this will more than likely happen to you in time. Do not expect it the first few times; this family bond is often earned with time.
