Personal distress alarms are very cheap, they are keyring devices that you pull the pin out and it screams at 130db for 90 minutes or so. Toss them down storm drains as the cops advance on you so they can't be turned off or destroyed

Get a few of these and lob them like sound grenades at the cops to disrupt their comms, or toss them onto the roof of the hotels where Ice are sleeping to keep them awake

    Do you have a link to these beauties?

    Just search for personal distress alarms, you can get them for $12 on Amazon (yuck), ~$5on AliExpress, and there are retail stores around me that sell them for ~$15-30.

    Most run at 130db, but the battery size, rechargeability and various other parameters vary a lot. If they are going to be treated as disposable, cheaper is better

    I would warn that these kinds of devices are serialized, so if the cops find them, then they can be used to trace back to you.

    This one?

    Here is a picture of the board for a relatively innocuous device, a tamogotchi.

    How many components in that one picture have a serial number, batch number, or marking that can be used to identify the component? I counted 10 at a cursory glance.

    Electronics devices aren't a monolith with a single serial number. Many components have markings on them to track it for QA and recalls.

    Serial numbers can be removed....

    You gonna crack the device open and remove any serial numbers on the components too? What about the board itself? Mfg and batch dates pressed into the inside of the casing?

    Do you think they match batch numbers to serial numbers with any sort of efficacy?

    Also what about people who resell and don't record the sale?

    Are they also a restricted item?

    IIRC, they caught some bomber based on a serial part of a radio he bought and repurposed components from.

    So yes. They do track that stuff. As for people who resell and don't record the sale, they can track the item to that person and then sweat the story out of them.

    Restricted or not, anything electronic you buy has a myriad of serial fingerprints on it that can narrow down the potential pool so suspects to a particular retail location and month.

    Edit : https://en.wikipedia.org/wiki/Pan_Am_Flight_103

    A circuit board fragment, allegedly found embedded in a piece of charred material, was identified as part of an electronic timer similar to one found on a Libyan intelligence agent who had been arrested 10 months previously for carrying materials for a Semtex bomb. The timer was allegedly traced through its Swiss manufacturer, Mebo, to the Libyan military, and Mebo employee Ulrich Lumpert identified the fragment at al-Megrahi's trial.
