Wrong.
These rules apply to search warrants, anybody who watches Law and Order should now the difference between a search warrent and gathering evidence at the scene of a crime.
I know I don't spend time watching Law and Order as you do, however the quote was "Defense attorney Hal Haddon has also said Colorado court rules call for hair, fibers and other "non-testimonial evidence" to be obtained during daylight hours."
As to probable cause, her blood on his shirt is not?
I guess it's obvious you don't understand the way things work.
There is NO rule about NOT searching for evidence at night, you just have to get the proper search warrent. If you want to search durring the day you get a day time search warrent, if you want to search at night you get a night time search warrent. Very simple, any cop should have known that and gotten the correct search warrent. Understand?
Probably cause is going to someone's house and noticing something while you were there standing in the door way (i.e. a gun laying on the sofa within eyesight). That would allow you to enter the residence/room without a search warrent or without the owners consent. Going to someone's home/room to actually enter and search for blood/hair evidence requires a search warrant. Understand?
Simple rules that apply to everyone not just the Lakers.
