62It should also be observed that, unlike crime, even particularly serious crime, a threat to national security must be genuine and present, or, at the very least, foreseeable, which presupposes that sufficiently concrete circumstances have arisen to be able to justify a generalised and indiscriminate measure of retention of traffic and location data for a limited period of time. Such a threat is therefore distinguishable, by its nature, its seriousness, and the specific nature of the circumstances of which it is constituted, from the general and permanent risk of the occurrence of tensions or disturbances, even of a serious nature, that affect public security, or from that of serious criminal offences being committed (see, to that effect, judgment of 6 October 2020, La Quadrature du Net and Others, C‑511/18, C‑512/18 and C‑520/18, EU:C:2020:791, paragraphs 136 and 137).
