No matter how fleeting the encounter, the DNA will hang around in their mouth for at least an hour. Things like chocolate, alcohol, and acidic drinks can make it easier for DNA to be broken down and washed away. The RNA will not affect your downstream applications (including PCR, SNP Genotyping, WES, or WGS) and can be removed, however it will affect quantitation of the DNA if quantifying only by absorbance. The DNA in saliva originates from cells that are shed from the inner linings of the mouth and from white blood cells. Because of that difference, DNA collected from a crime scene can either link a suspect to the evidence or eliminate a suspect, similar to the use of fingerprints. Before acting upon any of its information, you should obtain appropriate advice from a lawyer or other qualified professional.
