It does appear to be terrorism.

Yes.

And they've now made an arrest, in Dover.

Don't these bombers realise that with all the surveillance videos,
they're going to get caught?
It's not guaranteed.
Most criminals are caught due to having some form of previous
interaction with the Police and establishing the end of a trail, eg a
bank robbers trail may have started when he nicked some sweets from a
corner shop as a 13 year old and became one to watch and whose habits
and haunts become known.
With a terrorist the trail may have been started by intelligence
services observing their coming and goings with other known people
doing suspicious activity or being seen at certain buildings.
In both case if the perpetuator of a bank robbery or a terrorist act
is doing it for absolutely the first time and is a lone wolf it
becomes much harder, surveillance videos will not help if the person
in the image cannot be recognized or are disguised unless they happen
to turn up again elsewhere unguarded.
There are experts at analyzing videos but as an example of how
difficult it is to find someone with no previous look at the Jogger
who pushed the woman into the path of a Bus recently, not even
disguised, reasonable video from the street and the bus, loads of
people about.
They still have not identified anyone enough to bring charges

Indeed, and they've wrongly arrested two innocent joggers so far. You'd
think the jogger should be relatively easy to find, as his home location
can be pinned down to quite a narrow area, and he must have been caught by
many other cameras on his route.

As would the bomber. The only question would be how long it took to
back-track his movements. It takes people time - but he must have
boarded the train somewhere with his bucket-in-a-LIDL-bag.
