How are DNA samples obtained after an arrest?

Explanation:
DNA sampling after an arrest is typically done using a cheek swab because it provides a quick, non-invasive, reliable source of DNA from the cells lining the inside of the mouth. The swab collects epithelial cells with little discomfort, no needles, and can be processed rapidly by a lab to produce a DNA profile. While drawing a blood sample could yield DNA, it is more invasive, time-consuming, and not the routine method for arrestee processing. Hair follicle collection can work but depends on finding a suitable root and can be less reliable. Saliva samples are possible, but cheek swabs generally offer more consistent, high-quality DNA for analysis.
