Blue Line!

It's commonly called the "Blue Line,"
The people who enforce the law.
Their job's to protect the innocent,
They arrest and grab with the law's paw!

Their job will keep them apart from all,
Of the citizens they protect.
They can't mix with the innocents,
They're the ones that they sometimes collect!

Sometimes the job is just way too much,
Cause their daily work is with crime.
Dealing with low-lifes soon gets them,
They're united and they're the "Blue Line!!"
