Escalating violence during the crossings is the wrong approach.
We already collect many of the incoming migrants, so we can just change what we do when they arrive - to apprehend them rather than putting them in open accomodation in the community. Also, a huge number come in undetected into small ports - so the number we're hearing about is hugely underestimated - and that needs a separate prong of approach.
The only solution is to stop the pull factor. That means preventing people from disappearing into the black economy, far lower asylum acceptance, and quick deportation to somewhere they won't make a second attempt from (not France).
The asylum system urgently needs to be revisited. It was designed as a response to people fleeing war in Europe - into other European countries - and with very low global economic migration. The world is totally different now.
I think we need to completely re-think who we want to keep offering asylum to. Short-term asylum from a country temporarily at war - where we expect migrants to return to their country in their lifetime - yes. Chaotic country where most of the population have a terrible life and want to leave - and the physical journey to the UK is the only barrier to a much better life for a large part of the population (under the current asylum system) - no. We're just creating a market place for traffickers.
Denmark has started unilaterally making some of these changes - we need to do the same. The other European countries will catch up soon enough - this global migration crisis is only going to get worse.
Then we also need speedy deportation: If not Rwanda, then somewhere else. Although not Albania like Italy is doing: that's close enough and lawless enough that it's likely to become even more of a hub of people-trafficking than it already is.
And critically, the route into the black economy needs to close. People are suggesting ID cards and employer checks, but I'm not convinced that we could make that effective without a high imposition on the whole population, which means it would inevitably be watered down to the point it was easy to side-step. And it would be very expensive to implement.
My preference would be immediate deportation to an offshore waiting centre, coupled with far higher checks and surveillance at all UK ports, and satellite surveillance to intercept unauthorised entry. It would be far easier and cheaper to impose stricter checks on incoming vessels than to impose stricter checks on all employers and residents in the UK! We're surrounded by sea: let's make use of that!
