I don't know Texas law on it either, but I know in other states there are some misdemeanor exceptions carved out.JALLEN wrote:Generally, police cannot arrest, or cite, without a warrant, for a misdemeanor not committed in their presence. An officer can arrest without a warrant if he believes a felony has been committed and the person he arrests committed it, certainly a felony committed in his presence. I don't know the specific Texas law but I bet there is a code section that spells it out in detail.
Some states allow the officer to arrest without witnessing crimes like criminal child enticement, public indecency, domestic violence, violating a protection order, menacing by stalking, aggravated trespass, or a theft offense. Traffic tickets? I agree with you that they generally need to witness it or have pretty indisputable evidence (like video for example).
