I was working the Local Control West position and the weather was IFR and rainy. A B757 had just landed on Runway 9 and was rolling out when the ASDE triggered and said to send the aircraft around. The runway was free of equipment and/or other aircraft and I did not send the aircraft around. In my judgment the aircraft was safer on the ground; the target that the detection equipment generated for the aircraft was behind the aircraft's position on the runway; which I feel is the contributing factor to the false go around.
Local Controller elected not to issue a go around after receiving an AMASS alert noting the target activating the alert was behind the aircraft in question and no other runway traffic was observed.
