Law and Order (the original; mainly about court); Law and Order SVU (mainly about assaults); Law and Order Criminal Intent (mainly about murder cases); CSI; CSI Miami; CSI New York. I think there's also a second version of NCIS. There are also newer crime shows that I don't follow.
NCIS, Law And Order, Mid-Summer Murders, Inspector Luis, And CSI. I Know Cause My Parents Watch A Lot Of Those. Or At Least They Used Too. But Some Of Em Are Kinda Old & Lame.
