Why would you need hacking for that? Classic https://xkcd.com/538 nerd imagination.
Simply seize some devices and place the incriminating evidence on them. Or just place a device with incriminating evidence among other seized evidence. Crime shows make you think every item is individually serialized and bagged or whatever but in reality they're just going to make a bag labelled "15 SD cards and 6 USB sticks". Stuff like hard drives is just going to be "hard drive #6" in the log. Just swap the stickers, easy as pie. You think evidence is stored securely? Secure is expensive, and it's all stuff of guilty people anyway (otherwise it wouldn't be seized).
